1. INTRODUCTION
1.1 Clean Water Act
The 1972 amendments to the Federal Water Pollution Control Act (known as the Clean Water Act or
CWA), prohibit the discharge of any pollutant to waters of the United States unless the discharge is
authorized by a National Pollutant Discharge Elimination System (NPDES) permit. The CWA gives the
Environmental Protection Agency (EPA) the authority to enforce provisions of the act. The EPA, in
turn, has authorized state governments to perform many of the permitting, administrative, and
enforcement aspects of the NPDES Program.
The State of Montana has established a permit system which is essentially the equivalent of the federal
permit system, called the Montana Pollutant Discharge Elimination System (MPDES). This system is
administered by the Montana Department of Environmental Quality (MDEQ). The Administrative Rules
of Montana (ARM), section 17.30.1105 require that any entity discharging storm water from a point
source must obtain coverage under an MPDES general permit. MPDES general permits cover discharges
1) associated with construction activity; 2) associated with industrial activity; 3) associated with
mining, oil, and gas activity; 4) from small municipal separate storm sewer systems (small MS4s); 5) for
which the department determines that storm water controls are needed based on wasteload allocations
that are part of TMDLs that address the pollutants of concern; and 6) that the department determines are
contributing to a violation of a water quality standard or are significant contributors of pollutants to
surface waters.
1.2 Montana Designated Small MS4s
The EPA established guidelines for designating small MS4s, which MDEQ used to create the list of
Montana small MS4s named in ARM 17.30.1102(23) – the Urban Areas (as determined by the latest
decennial census by the United States census bureau) of the city of Billings and Yellowstone County;
the city of Missoula and Missoula county; and the city of Great Falls and Cascade county. In addition,
MS4s located within the cities of Bozeman, Butte, Helena, and Kalispell were also named because their
discharge “results in, or has the potential to result in, exceedances of water quality standards, including
impairment of designated uses, or has other significant water quality impacts, including habitat and
biological impacts”.
Municipalities within the Missoula Urban area which own and operate separate storm sewer systems are
the City of Missoula, Missoula County, Montana Department of Transportation – Missoula Office, and
the University of Montana.
1.3 General Permit
The General Permit for Storm Water Discharge Associated with Small Municipal Separate Storm Sewer
Systems provides authorization to discharge storm water to waters of the United States under the
Montana Pollutant Discharge Elimination System. The General Permit, under the authority of ARM,
Missoula SWMP 2008 Annual Report
Section 1 – Introduction; Page 1
defines effluent limitations; establishes monitoring, recording, and reporting requirements; establishes
requirements for a Storm Water Management Plan (SWMP); and sets standard permit conditions. The
General Permit, along with the associated Environmental Assessment, Fact Sheet, and authorization
letter can be found in Appendix H of this report. Additional MPDES information can be found on the
Montana Department of Environmental Quality website: http://www.deq.mt.gov/wqinfo/MPDES/.
The goal of the General Permit is to reduce the discharge of pollutants to the maximum extent
practicable (MEP) to protect water quality and to satisfy the appropriate water quality requirements of
the Montana Water Quality Act. The permit requires a storm water management program that addresses
the following issues: 1) specify Best Management Practices (BMPs) for six minimum control measures;
2) identify measurable goals for these control measures; 3) develop an implementation schedule for
these control measures; and 4) define the responsible entity to implement these control measures. The
EPA has defined the six minimum control measures as follows: 1) Public Education and Outreach on
Storm Water Impacts, 2) Public Involvement/Participation, 3) Illicit Discharge Detection and
Elimination, 4) Construction Site Storm Water Runoff Control, 5) Post-Construction Storm Water
Management in New Development and Redevelopment, and 6) Pollution Prevention/Good
Housekeeping for Municipal Operations. According to ARM and the General Permit, “implementation
of Best Management Practices (BMPs) consistent with the provisions of the SWMP and the
requirements of the general permit shall constitute compliance with the requirements of reducing
pollutants to the MEP”.
1.4 Missoula’s Co-permittee Plan
ARM and the General Permit allow for the sharing of responsibilities; as such, the Missoula small MS4
operators have applied for and received coverage under one permit. With the goal of producing the best
possible SWMP for the Missoula Area, the co-permittees have collaborated their knowledge, ideas, and
resources. General Co-permittee responsibilities were determined during the permit process and the map
on page four of this document illustrates these boundaries. More detailed responsibilities and written
obligations are outlined in an Interlocal Agreement as well as the SWMP. A modified matrix of BMPs is
included in Appendix F of this document.
As the co-permittees work together to achieve the common goal of clean storm water, each will retain
jurisdiction over its own small MS4, maintain its own records, and provide information for a common
report. Boundaries established at the time of the permit application were based on ownership
information that was current as of February 13, 2006. See map on page 4 of this section.
The Montana Department of Transportation owns four parcels and maintains numerous major traffic
routes through the urbanized area, which contain a variety of drainage systems, some of which discharge
to the Clark Fork and Bitterroot Rivers.
The University of Montana owns many parcels near the main campus as well as a few parcels at remote
campuses. Its storm drain system is limited to two small piped systems with minor outfalls into the Clark
Fork River, and injection wells.
Missoula SWMP 2008 Annual Report
Section 1 – Introduction; Page 2
The City of Missoula has responsibility for all areas within the city limits that are not owned by either
the Department of Transportation or the University of Montana. The City owns and operates three fully
functional small storm drain systems located in the Downtown area, Linda Vista/Maloney Ranch area,
and Farviews area. The City and County jointly own and the City operates a larger storm drain pipe
system in the South Hills area. These systems discharge to the Clark Fork and Bitterroot Rivers. In
addition to these systems, the City also operates and maintains a variety of storm drain sumps, drainage
swales, retentions ponds, and minor piped systems without outfalls to surface water, designed for
managing storm water runoff and surface water quality.
Missoula County has responsibility for all areas outside of the city limits, but within the urbanized area,
which do not belong to either Department of Transportation or the University of Montana. The County
owns jointly with the City and has arranged for the City to operate a large piped storm drain system that
discharges to the Bitterroot River. The County also owns and operates a small piped system with an
outfall to Butler Creek. A variety of injection wells, drainage swales, and retention ponds are also
operated and maintained by the County.
1.5 Annual Report
In accordance with Part IV, Section I of the General Permit, permittees are required to submit annual
reports of activities associated with the Storm Water Management Program. This is the third reporting
period and covers the time from January 1, 2008 through December 31, 2008. The Annual Report
provides an update of efforts made by the Missoula Co-permittees in implementing the measures and
programs set forth in the SWMP.
Because the four Missoula-area small MS4 operators have applied as co-permittees and agreed to share
responsibilities, this report contains information for all operators. The report is organized so that the
responsible entity can sign for the BMPs for which it was required to implement, but the report must be
considered in its entirety in order to be complete.

2.1 Public Education and Outreach on Storm Water Impacts
2.1.1 Status of Compliance with Permit Conditions (General Permit requirement Part IV.I.1)
2.1.1.1 Requirement/Minimum Measure: Implement a public education program to distribute educational
materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges
on water bodies and the steps that the public can take to reduce pollutants in storm water runoff.
Best Management Practice: Community watershed education.
Measurable Goal: Continue to support the existing community watershed education program at the 6th grade
level.
Status: In 2008 the Water Quality District (WQD) supported the Annual Watershed Festival organized by The
Montana Natural History Center. Through this program, approximately 600 sixth-graders learn about conditions
within our watershed and factors that affect water quality. This is done through a combination of classroom visits
and time spent at the various stations at the festival. Water Quality District staff presented the Enviroscape
Watershed Model, which explains point and non-point source pollution and their effects on surface water quality.
Students also learn how Best Management Practices can treat storm water runoff and protect surface water.
The Water Quality District and City of Missoula Wastewater Treatment Plant provided financial support to the
Watershed Education Network to provide classroom and field education to students throughout the Clark Fork
Watershed about surface and groundwater issues. Students learn how to assess surface water quality through
macro-invertebrate identification and stream assessments of physical and chemical conditions.
In 2008, the Watershed Education Network’s School Water Monitoring Program provided a total of 2248 student
days of education from 107 classrooms. Students collected water quality and quantity data from stream reaches
within the Clark Fork River Basin. WQD staff assisted with several of these fieldtrips.
WQD sponsored a booth at Missoula’s first “Earth Day, A Missoula Celebration”. WQD staff was available to
answer water quality questions and conducted demonstrations of the Aquifer Model.
In 2008, the Water Quality District continued promotion of a riparian area awareness campaign. Fliers were
distributed throughout the county and ads were placed in the Missoula Independent and the Missoulian. One
major contribution of healthy riparian areas is their ability to treat and reduce the effects of contaminated surface
water runoff. Riparian vegetation also stabilizes soil and prevents erosion. Several of these ads focused on the
stabilization and filtering capabilities of riparian areas. WQD placed a number of radio ads as part of this
campaign.
2.1.1.2 Requirement/Minimum Measure: Implement a public education program to distribute educational
materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges
on water bodies and the steps that the public can take to reduce pollutants in storm water runoff.
Best Management Practice: MVWQD educational pamphlets and utility stuffers.
Measurable Goal: Continue the existing annual distribution of MVWQD educational pamphlets and utility
stuffers for household and hazardous waste management and disposal related to water quality protection.
Status: In 2008 the Water Quality District printed and distributed approximately 1000 sets of brochures to
participants in the Annual Household Hazardous Waste Collection Event. Members of the public received the
following brochures: Alternatives to Household Toxics, Managing Leftover Paint, and A Residential Guide to the
Missoula Valley Aquifer. This material includes information on recycling and proper disposal of household toxics.
It also informs readers of the hazards associated with improper waste disposal. Copies of educational pamphlets
and utility stuffers can be found in Appendix A, starting on page A-1.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 1
2.1.1.3 Requirement/Minimum Measure: Implement a public education program to distribute educational
materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges
on water bodies and the steps that the public can take to reduce pollutants in storm water runoff.
Best Management Practice: Potential collaboration with Mountain Water Company.
Measurable Goal: Explore potential collaboration with Mountain Water Company for public education
purposes.
Status: Mountain Water Company has been instrumental in generating aquifer awareness and has assisted the
Water Quality District by advertising the annual Household Hazardous Waste Collection through their utility bills.
2.1.1.4 Requirement/Minimum Measure: Implement a public education program to distribute educational
materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges
on water bodies and the steps that the public can take to reduce pollutants in storm water runoff.
Best Management Practice: MVWQD TV, PSA and printed advertising
Measurable Goal: Continue and modify as necessary MVWQD’s TV, radio, printed advertising and street sign
public education program.
Status: The Water Quality District and the City of Missoula Wastewater Treatment Plant have continued to place
periodic educational ads in both the Missoulian and the Missoula Independent. Ads address the effects of
improper disposal of these items and offer appropriate options for disposal as well as emphasize purchase of
less-toxic alternatives. Readers are reminded never to dispose of waste through storm drains. In 2008, ads were
placed in both the Missoulian and the Missoula Independent addressing proper disposal of various household
toxics.
Television advertising is primarily centered on the Annual Household Hazardous Waste Collection and Earth Day.
Each year the WQD places approximately 160 television spots during Earth Week. These ads focus on non-point
source pollution and effects on surface water quality with regards to leaking vehicles and over-application of lawn
chemicals. During the weeks preceding Hazardous Waste Days, the ads focus on the importance of proper waste
disposal while advertising the collection event. One ad portrays various residents using a storm drain for disposal
of paints, antifreeze and lawn clippings and explains that these contaminants find their way into surface water and
drinking water supplies.
In 2008, the Water Quality District continued promotion of a riparian awareness campaign. Fliers were distributed
throughout the county and ads were placed in the Missoula Independent and the Missoulian. One major
contribution of healthy riparian areas is their ability to treat and reduce the effects of contaminated surface water
runoff. Riparian vegetation also stabilizes soil and prevents erosion. Several of these ads focused on the
stabilization and filtering capabilities of riparian areas. WQD placed a number of radio ads as part of this
campaign.
Periodically, Public Service Announcements (PSA’s) are placed with local radio stations. The Water Quality
District also runs 225 ads during Hazardous Waste Days over 15 local radio stations to publicize the collection
event.
2.1.1.5 Requirement/Minimum Measure: Implement a public education program to distribute educational
materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges
on water bodies and the steps that the public can take to reduce pollutants in storm water runoff.
Best Management Practice: City’s annual Street Cleaning Program
Measurable Goal: Continue to distribute approximately 17,000 flyers annually to property owners and
residents inside the city limits via the local newspaper describing the Street Cleaning Program, its benefits and
schedule.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 2
Status: In 2008, 19,600 flyers were distributed in the Missoulian on March 18th. A copy of the flyer can be found
in Appendix A, beginning on page A-9.
2.1.1.6 Requirement/Minimum Measure: Implement a public education program to distribute educational
materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges
on water bodies and the steps that the public can take to reduce pollutants in storm water runoff.
Best Management Practice: City’s annual Street Cleaning Program
Measurable Goal: Continue to distribute approximately 5,600 door hangers annually to property owners and
residents in target parking areas describing the Street Cleaning Program, its benefits and schedule.
Status: A local Boy Scout troop distributed the door hangers a week before the first scheduled cleaning in the
area. In addition, extra flyers are available at City Hall and the Streets Division office. In 2008, 7,000 door hangers
were delivered in March, April, and May. Door hangers are identical to newspaper flyers and can be found in
Appendix A, beginning on page A-9.
2.1.1.7 Requirement/Minimum Measure: Implement a public education program to distribute educational
materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges
on water bodies and the steps that the public can take to reduce pollutants in storm water runoff.
Best Management Practice: Agency websites
Measurable Goal: Continue the updating and maintenance of existing water quality information on the website
for the City.
Status: The City storm drain map has been posted on the internet with a link from the City website. The goal is
to increase awareness of locations of storm drain inlets, as well as illustrate the direct relationship between the
storm drain system and our rivers and streams. A link has been created to the previous years' SWMP Annual
Reports, and this year's report will be linked as well. Each introduction section gives a basic background of the
MPDES program and an overview of the co-permittees’ responsibilities. Interested citizens can contact copermittees to get more information or find out how they can become involved. In addition, there is a link from the
City website to the Missoula Valley Water Quality District: http://www.co.missoula.mt.us/wq/. The site educates
readers on proper recycling and disposal of household toxics, reducing the amount of waste, and the use of lesstoxic alternatives.
The City is in the process of updating its website and a more comprehensive storm water page will be included.
The newly introduced City Subdivision Guide and Toolbox will still be available on the new site. The Toolbox
contains links to standard drawings, relevant administrative rules, forms, checklists, the urban area storm drain
map, etc. Information pertaining to construction site storm water runoff control measures as well as postconstruction storm water management in new development and redevelopment are included.
2.1.1.8 Requirement/Minimum Measure: Implement a public education program to distribute educational
materials to the community or conduct equivalent outreach activities about the impacts of storm water discharges
on water bodies and the steps that the public can take to reduce pollutants in storm water runoff.
Best Management Practice: Water Quality Advisory Council
Measurable Goal: Continue the existing Water Quality Advisory Council of the MVWQD. Increase WQAC
knowledge regarding NPDES-MPDES permit requirements and Missoula’s storm water management plan
development process.
Status: The Water Quality Advisory Council continues to meet monthly to discuss issues affecting groundwater
and surface water.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 3
2.1.2 Results of Information Collected and Analyzed (General Permit requirement Part IV.I.2)
During 2008, no information related to Public Education and Outreach on Storm Water Impacts was collected and
analyzed.
2.1.3 Storm Water Activities for 2009 (General Permit requirement Part IV.I.3)
The City of Missoula will continue all of its Public Education and Outreach BMPs from the previous reporting
cycle. Through the Missoula Valley Water Quality District (MVWQD), area sixth grade students will study
watershed essentials. MVWQD will continue the annual distribution of its educational pamphlets and utility stuffers
for household hazardous waste disposal related to water quality protection. The Co-permittees and MVWQD will
continue to collaborate with Mountain Water for public education purposes. MVWQD will continue to advertise via
TV, radio, and newspaper, in addition to continuing its street sign public education program. These programs will
be modified as needed. The City of Missoula will distribute approximately 17,000 flyers to property owners and
residents inside the city limits via the local newspaper describing the Street Cleaning Program, its benefits and
schedule. In addition, approximately 5,600 door hangers will be distributed to property owners and residents in
target parking areas describing the Street Cleaning Program, its benefits, and schedule. The link from the City
website to the regularly updated Storm Water map will be maintained, as well as the link to the MVWQD website.
The existing Water Quality Advisory Council of the MVWQD will continue to be used as a resource for Missoula’s
storm water management plan development process. See Appendix G for Storm Water BMP implementation
schedule.
2.1.4 Proposed Changes to the SWMP (General Permit requirement Part IV.I.4)
No changes to the Public Education and Outreach portion of the Storm Water Management Plan are being
proposed at this time.
2.1.5 Notice of Reliance on Another Government Entity (General Permit requirement Part IV.I.5)
The City of Missoula will not be relying on any other government entity for the implementation of its Public
Education and Outreach BMPs.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 4
2.2 Public Involvement/Participation
2.2.1 Status of Compliance with Permit Conditions (General Permit requirement Part IV.I.1)
2.2.1.1 Requirement/Minimum Measure: Comply with state and local public notice requirements when
implementing a public involvement/participation program.
Best Management Practice: Water Quality Advisory Council, City Council, County Commissioners and
Neighborhood Council participation
Measurable Goal: Work with and through these local governing bodies to expand, improve and assist with
Storm Water Management Program planning and implementation.
Status: All city agencies comply with public notice requirements established in Section 2-3-203(1) MCA.
Missoula Valley Water Quality District Meetings are publicized via email to interested parties and are posted in
public locations prior to the meeting. Beginning in 2007 the Water Quality Advisory Council schedule for the year
will be published in the Missoulian as well as on the Missoula County Board of Health’s website.
According to the Missoula Municipal Code, Chapter 2.06.030, “The city council shall hold regular meetings on the
first, second, third and fourth Mondays of each month, at an hour set forth in the city council rules.” City personnel
send out general press releases to all area newspapers, and TV and radio stations announcing meeting times
and locations. City council meetings are also announced on the city webpage. A local TV network, MCAT, also
televises many of the meetings.
Neighborhood Council meetings are announced on the city webpage and on sandwich boards placed throughout
neighborhoods about a week before meetings.
2.2.1.2 Requirement/Minimum Measure: Comply with state and local public notice requirements when
implementing a public involvement/participation program.
Best Management Practice: Volunteer and citizen-student groups
Measurable Goal: Continue to work with and utilize volunteer and citizen-student groups to work on existing
best management practices such as:
- The annual Household Hazardous Waste collection event
- Consider re-stenciling of storm drains
Work with these groups to help identify new BMPs suitable to the community's needs
Status: Each year since 1993 the Missoula Valley Water Quality District with the City of Missoula Wastewater
Division has held a Household Hazardous Waste Collection Event. Many unwanted hazardous and toxic materials
are accepted from Missoula County Residents for no charge, including oil-based paints and stains, paint thinner,
degreasers, gasoline, other flammable liquids, aerosol paints, fertilizer and non-alkaline household batteries. The
table on page B-1 of Appendix B lists the amounts of hazardous waste collected at the 2008 event.
In 2004, a mercury thermometer collection and exchange campaign was started. Each household that brought
one or more mercury thermometers to the Household Hazardous Waste collection day is given a coupon for one
free digital thermometer to be picked up at a participating store. The campaign was such a success in 2004 that it
has been continued in subsequent years.
The Water Quality District coordinates volunteer efforts for the annual Household Hazardous Waste Collection.
Volunteers are recruited from the University of Montana, local environmental consultants, interested citizens and
other local businesses. In 2008, 35 volunteers assisted with the collection.
Periodically storm drains are stenciled or re-stenciled to remind residents never to dispose of waste through storm
drains. In 2007 storm drains in the university area were stenciled through an Earth Day project by university
students. Also, the Lolo Watershed Group stenciled storm drains in that community as a part of Earth Day
activities. A picture of a stenciled storm drain can be found on page B-2 of Appendix B.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 5
2.2.1.3 Requirement/Minimum Measure: Comply with state and local public notice requirements when
implementing a public involvement/participation program.
Best Management Practice: City's Urban Reforestation Program
Measurable Goal: Continue the City’s program for urban area reforestation for the purposes of soil
stabilization.
Status: Tree roots stabilize soil and play an important and effective role in soil conservation, erosion control, and
flood control. In addition, trees transpire considerable amounts of water daily, and neutralize wastewater which
passes from the surface to the aquifer. Missoula has an extensive urban forest (approximately 20,000 trees),
most of which is planted in residential boulevards. The City plants and maintains the public trees, while adjacent
homeowners provide regular water. Developers are required to plant boulevard trees in new subdivisions as well,
ensuring the expansion of the urban forest. Both of these requirements are outlined throughout Title 12 of the
Missoula Municipal Code. Without the help of citizens, City personnel would not be able to maintain such an
extensive urban forest.
The City's Urban Forestry Division offers programs that encourage the planting of trees. A website maintained by
the division gives information about these programs as well as guidelines for watering, tree selection for our
climate, and sources of help for unhealthy trees. Educational flyers are also available at the Urban Forestry office.
Copies of the fliers can be found in Appendix B, starting on page B-3. The City also encourages citizen
participation in urban reforestation by sponsoring a road race each year in association with Arbor Day. Each
participant receives a tree seedling to plant at their homes. In 2008, approximately 600-700 seedlings were given
away.
2.2.1.4 Requirement/Minimum Measure: Comply with state and local public notice requirements when
implementing a public involvement/participation program.
Best Management Practice: City Federal Aid road improvement projects
Measurable Goal: Continue project NEPA public involvement compliance process for each Federal Aid project
Status: During 2008, the City had one Federal Aid road improvement project, Russell Street / South Third Street
West Draft Environmental Impact Statement, in the public involvement phase. During the year, there was a public
hearing as well as an open comment period. The engineering consultant retained to perform the Environmental
Impact Statement was also responsible for all public notices. Paid advertising, television, direct mailing, internet,
newspaper, and radio where all used to notify the public of the hearing as well as the comment period. In addition,
a notice of availability for the DEIS was printed in the Federal Register on August 29th.
2.2.2 Results of Information Collected and Analyzed (General Permit requirement Part IV.I.2)
The city of Missoula continues to have steady public participation in the Household Hazardous Waste Collection
Day. This participation includes volunteers and folks conscientiously disposing of their hazardous wastes.
Success of the program has been seen in several ways: 1) The quality of containers holding the liquids to be
disposed of has improved. We rarely see the rusty leaking unlabeled can or the pickup truck full from years of
storing unwanted waste. 2) We are seeing a trend toward less oil based paints to pesticide related products
indicating folks are buying less, using up, and/or using less hazardous paint products. 3) The volume of banned
pesticides brought to the collection day has decreased.
2.2.3 Storm Water Activities for 2009 (General Permit requirement Part IV.I.3)
The City of Missoula will continue all of its Public Involvement/Participation BMPs from the previous reporting
cycle. City/county personnel and/or elected officials will meet with Neighborhood Councils and the Water Quality
Advisory Council to expand, improve, and assist with the Storm Water Management Plan. Volunteer and citizenstudent groups will continue to be solicited for help with projects such as the annual Household Hazardous Waste
collection event and storm drain stenciling. These groups will also be asked for ideas about new BMPs suitable to
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 6
the community’s needs. The City's Urban Forestry Division will continue to educate citizens about the importance
of trees in soil stabilization. Federal Aid road improvement projects will continue the NEPA public involvement
compliance process. See Appendix G for Storm Water BMP implementation schedule.
2.2.4 Proposed Changes to the SWMP (General Permit requirement Part IV.I.4)
No changes to the Public Involvement/Participation portion of the Storm Water Management Plan are being
proposed at this time.
2.2.5 Notice of Reliance on Another Government Entity (General Permit requirement Part IV.I.5)
The City of Missoula will not be relying on any other government entity for the implementation of its Public
Involvement/Participation BMPs.

2.3 Illicit Discharge Detection and Elimination Measures
2.3.1 Status of Compliance with Permit Conditions (General Permit requirement Part IV.I.1)
2.3.1.1 Requirement/Minimum Measure: Develop, if not already completed, a storm sewer system map,
showing the location of all outfalls and the names and locations of all outfall receiving waters.
Best Management Practice: Urban Area Storm Drain System Map development
Measurable Goal: Review each agency’s existing maps and records. Ground truth all systems and discharge
points identified on the existing maps and in records for each agency. Complete the mapping in each agencies
jurisdictional areas and combine all into one comprehensive Urban Area Storm Drain System Map.
Status: The City's storm system map was initially developed using a georeferenced aerial photo taken in 2004
as the basemap. Updates have been made based on a more accurate aerial photo taken in the spring of 2006.
The storm water assets were located using a combination of engineers’ project drawings, historical maps, and
field verification. The water features were located using a 1999 aerial photo from which streets, waterways, and
contour lines were generated.
City staff has merged data from all four co-permittees to form a comprehensive Urban Area Storm Drain System
Map. The City and County will work cooperatively to require as-built drawings at project close-out. The as-built
drawings will be stored in digital format and available for staff and public viewing via the internet. In addition, the
drawings will be used to update the map with new systems, while staff will continue ground-truthing to verify
existing systems. A copy of the current storm sewer map can be found in Appendix C, page C-1.
2.3.1.2 Requirement/Minimum Measure: To the extent allowable under state or local law, effectively
prohibit, through ordinance or other regulatory mechanism, non-storm water discharges (other than the potential
non-storm water discharges for MS4s listed in New Rule VII (6) (c) (iii) into the MS4 and implement appropriate
enforcement procedures and actions.
Best Management Practice: Code enforcement existing and future
Measurable Goal: Continue enforcing municipal water quality ordinances. Review, combine, edit and develop
new ordinances as necessary to meet this requirement. Implement enforcement of new laws and procedures
immediately after adoption.
Status: In 2000, the Missoula City Council adopted the Missoula Valley Water Quality Ordinance, which is
intended to protect the public health, safety, and general welfare of those utilizing the Missoula Valley Aquifer and
surface waters in the Missoula Valley for drinking water, recreation, and other beneficial uses. The provisions of
the ordinance were deemed to be a health ordinance and as such are to be applied to an area within five miles
outside of the city limits.
The ordinance establishes prohibitions and restrictions to prevent surface water and groundwater contamination,
and to protect public health, safety, and welfare by regulating “Regulated Substances”. Regulated Substances are
defined as “any liquid substance, semi-liquid substance, or soluble solid on the most current Superfund
Amendments and Reauthorization Act (SARA), Title III List of Lists published by the Office of Pollution Prevention
and Toxic Substances, U.S. Environmental Protection Agency, Washington D.C., any petroleum product, any
hazardous waste, or any other substances that the Board of Directors of the Missoula Valley Water Quality
District determines, following public review, may threaten contamination of the Missoula Valley Aquifer, excluding
substances used for personal household use.”
The ordinance also gives MVWQD the authority to perform inspections and enforce the provisions of the
ordinance. In 2008, the Water Quality District responded to 20 water quality complaints. Two employees of the
Water Quality District serve in an on-call position for the Environmental Health Division hazardous materials
response program. An employee of the division is on-call at all times. When dispatched by 911, employees work
to minimize the threat to the public and the environment that may be present. Vehicle accidents and hazardous
material spills are managed to reduce the potential of groundwater, surface water, soil and air contamination.
Storm drains are of particular concern and every effort is made to prevent spills from reaching the inlet. If the spill
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 8
does reach the storm drain, Fire Department, Health Department and Hazardous Material Team Members are
trained in the use of booms and are equipped with sorbent pads to capture as much material as possible. The
City of Missoula streets department has also assisted in cleanup of some spills.
In an effort to prevent dumping to the storm drain, newly constructed or replaced storm drain manhole covers and
dry well covers are required to conform to City of Missoula standard drawings. The new covers are clearly marked
“Dump No Waste” and “Drains to Streams” or “Drains to Waterways”, and also display a trout logo. The standard
drawings can be found in Appendix C starting on page C-2.
2.3.1.3 Requirement/Minimum Measure: Develop and implement a plan to detect and address non-storm
water discharges, including illegal dumping, to the MS4.
Best Management Practice: Plan for monitoring discharge points.
Measurable Goal: Work together to select the appropriate techniques to monitor and detect non-storm water
discharges, trace to source, and mitigate in accordance with new laws.
Status: Co-permittees met to discuss fulfilling this requirement with a unified approach. Based on the Center for
Watershed Protection's "Illicit Discharge Detection and Elimination" manual and advice from Missoula Valley
Water Quality District Staff, co-permittees agreed to begin by performing a dry weather inventory, taking pictures
and documenting any discharges. Older sections of town were targeted as high priorities.
The Missoula Valley Water Quality District assisted co-permittees with sampling. And Missoula's wastewater
treatment plant lab performed testing. For any tests the treatment plant was not able to perform, they arranged for
an outside lab to perform the tests. Since much of the Missoula Valley is located close to the aquifer, ground
water is commonly found in storm drain pipes. Testing will help to differentiate between discharges containing
only groundwater and those containing contaminants.
City staff walked approximately 6.8 stream bank miles of the Clark Fork River and 6.6 stream bank miles of
Rattlesnake Creek within the city limits of the urban area. A total of 31 outfalls were found and documented. A
Center for Watershed Protection Outfall Reconnaissance Inventory/Sample Collection Field Sheet was filled out
and a picture taken for each. Seven of the outfalls had discharges, and samples were taken at each of these.
Based on the Center for Watershed Protection's "Illicit Discharge Detection and Elimination" manual and the
MPDES permit requirements, samples were tested for total suspended solids, chemical oxygen demands, total
phosphorus, total nitrogen, pH, ammonia, E. Coli, total coliform, chlorine, surfactants, and potassium. Results of
sampling can be found in Appendix C, page C-4. All outfalls and associated information are being tracked in the
City's asset management database.
A meeting was held with representatives from the Missoula Valley Water Quality District and the Wastewater
Treatment Plant Lab to discuss the results of the sampling. Four of the samples were thought to contain
something other than ground water. For each of those sites, a course of action was devised as follows.
Outfall SNA-1526 is located on the Clark Fork River near the downtown railroad bridge. It was found to have
chlorine levels similar to tap water typical to Missoula. Since none of the other parameters appear out of the
typical range, tap water is the primary suspect. This outfall will be retested during the next dry weather season to
determine if the previous results can be reproduced. If there still appears to be tap water in the storm drain, a
surface investigation will be performed and a TV inspection will be employed (if required) to locate the source of
the discharge.
Outfall UNK-15 is located on an irrigation ditch near the University of Montana and the Madison Street Bridge. It
was found to have unusually high levels of chlorine (0.60 mg/L, compared to typical tap water which is 0.12 mg/L).
Representatives of Mountain Water Company believe the pipe is the discharge line from a well pump control
valve. Mountain Water Company reports that their typical chlorine residual is a minimum of 0.2 ppm. To maintain
that, they typically dose at around 0.35 ppm. Since this doesn't account for such high levels of chlorine, we will
retest during the next dry weather season to determine if the previous results can be reproduced. If chlorine levels
are still found to be high, representatives of Mountain Water Company and the Missoula Water Quality District will
meet on site to see if the source can be determined. A TV inspection will be employed if necessary.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 9
Outfall SNA-1519 is located near UNK-15 on an irrigation ditch. It was found to have unusually high levels of
COD, turbidity, nitrogen, and potassium. This pipe drains a small area of university campus as well as one block
of residential street. A sewage lift station, which was replaced during the summer, is also located within the
drainage area. Construction within the drainage area is suspected to be the cause of the higher than average
numbers, so the outfall will be retested during the next dry weather season to see if stabilization of the
construction site has any affect on the results.
Outfall SNA-1521 is located on the Clark Fork River, downstream from the Higgins Street Bridge. It was found to
have unusually high levels of total coliform colonies and nitrogen. No E. Coli colonies were found, so sewage is
not the source of the discharge. Since total coliform colonies can be found in a variety of situations, and other
numbers do not appear to be out of the normal range, it's difficult to theorize what the source of the discharge
could be. City staff will retest the outfall during the next dry season to determine if the coliform numbers can be
duplicated or if other parameters will give more insight.
If illicit discharge is found and the source is identified as a private source, MVWQD will work with the property
owner(s) to correct the issue. Water Quality District Staff will rely on Missoula Municipal Code Section 13.26.080
which makes it "unlawful for any person to cause contamination or to place, cause to be placed, or allow to
remain in place any substance in a location where it is likely to cause contamination" if the owner fails to
cooperate. This ordinance can be updated or additional ordinances written if experience shows this rule to be
inadequate to address illicit discharge issues.
Outfalls which are thought to contain only ground water will continue to be monitored next year, but will not be
resampled. Priority areas for dry weather inventory next year will include Pattee Creek, Grant Creek, and the
short section of the Bitterroot River within the City's MPDES jurisdiction.
The MVWQD systematically eliminated all automotive shop sumps not connected to sanitary sewer some years
ago. It was common practice in the past for automotive shops to install an infiltration sump to dispose of waste
automotive fluids. This type of injection well has been linked to groundwater contamination. In the early 1990’s
the Missoula City county Health Department inventoried these shops and disposal wells and began the process of
abandoning them. Though inventoried wells have been properly abandoned, the district occasionally encounters
open wells during complaints and inspections. The district works with property and business owners to promptly
remediate and close injection wells.
2.3.1.4 Requirement/Minimum Measure: Inform public employees, businesses, and the general public of
hazards associated with illegal discharges and improper disposal of waste.
Best Management Practice: MVWQD educational pamphlets and utility stuffers.
Measurable Goal: Continue the existing annual distribution of MVWQD educational pamphlets and utility
stuffers for household and hazardous waste management and disposal related to water quality protection as
described above.
Status: In 2008 the Water Quality District printed and distributed approximately 1000 sets of brochures to
participants in the Annual Household Hazardous Waste Days. Members of the public received the following
brochures: Alternatives to Household Toxics, Managing Leftover Paint, and A Residential Guide to the Missoula
Valley Aquifer. This material includes information on recycling and proper disposal of household toxics. It also
informs readers of the hazards associated with improper waste disposal. Copies of educational pamphlets and
utility stuffers can be found in Appendix A, starting on page A-1.
2.3.1.5 Requirement/Minimum Measure: Inform public employees, businesses, and the general public of
hazards associated with illegal discharges and improper disposal of waste.
Best Management Practice: MVWQD’s 1996 Evaluation of Unsewered Areas in Missoula, City’s 1999
Update of the Wastewater Facility Plan and Voluntary Nutrient Reduction Program (VNRP) agreement.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 10
Measurable Goal: Continue implementing the extension of municipal sanitary sewer to the priority areas
identified in the Unsewered Areas Evaluation and the projects identified in the City’s Wastewater Facility Plan as
well as the City’s goals for abandoning septic systems under the VNRP.
Status: In 2008, approximately 11.3 miles of sewer main were added to the municipal sanitary sewer system,
which is located in city jurisdiction as well as county. With this, 363 stubs were created for future connection, 151
buildings were connected (including commercial and multi-family), and 99 buildings were removed from their
existing septic systems and connected to municipal sewer. In 2007, the City of Missoula passed revisions to
Chapter 13.04: Sewer Regulations. The revisions require connection to public sanitary sewer upon property
transfer for any properties within city limits where public sanitary sewer is available.
2.3.1.6 Requirement/Minimum Measure: Inform public employees, businesses, and the general public of
hazards associated with illegal discharges and improper disposal of waste.
Best Management Practice: City’s Biological Nutrient Reduction Program
Measurable Goal: Continue the work to upgrade the municipal wastewater treatment facility’s BNR system.
Status: Phosphorus and Nitrogen annual average removal for 2008 were 88% and 70% respectively. The
WWTP regularly performs plant tours for the public and City employees. Through the Wastewater Treatment
Plant's involvement with the Voluntary Nutrient Reduction Program (VNRP) and having a current membership on
the Tri-State Water Quality Council there is a continuous commitment to educating and engaging residents to take
an active role in protecting water quality and reducing pollution.
The Pretreatment Program, Missoula Valley Water Quality District, and a local environmental group, Women's
Voices for the Earth, worked together to educate and promote voluntary participation in BMPs at dental offices.
The efforts have resulted in 91% of the dentists returning participation forms and 82% of doctors having installed,
or planning to install by 2009, an amalgam separator.
2.3.2 Results of Information Collected and Analyzed (General Permit requirement Part IV.I.2)
During 2008, four storm water samples were collected – two from our residential outfall and two from our
commercial/industrial outfall. A copy of the results can be found in Appendix A, starting on page A-11.
Both samples taken at the residential outfall recorded exceedances in chemical oxygen demand. One sample
was over the median concentration in total nitrogen, and the other in total phosphorus. In 2007, one sample from
this outfall recorded similar numbers and at that time, we took an educational approach to the issue. Being a
residential area, yard waste, fertilizers, and pet waste were suspected to be the problem. The Missoula Valley
Water Quality District purchased TV, radio, and newspaper ads in an attempt to educate the public of potential
storm water contaminants associated with these items. According to samples taken in 2008, these measures did
not appear to have significant impacts on this outfall's water quality. In 2009, the City will attempt to determine if
these numbers are indicative of all residential neighborhoods, or only those neighborhoods in newer subdivisions,
by sampling an additional outfall in an older neighborhood. The theory is that this new neighborhood does not
accurately represent older neighborhoods in which lawns are established and erosion is somewhat more
controlled. This may also indicate that this outfall's samples will improve as the subdivision becomes established
and stabilized.
The two samples taken from the commercial/industrial outfall were very different from each other. The first sample
taken in June showed all parameters below the median concentration, within desired pH range, and below the
standard value for oil and grease. The second sample taken in November was not as clean, however. It exceeded
median concentrations for chemical oxygen demand and total nitrogen as well as being above the standard value
for oil and grease. Generally, these results are better than the previous samples from 2007, though. During 2008,
the Montana Department of Transportation cleaned the detention basin, which probably accounts, at least in part,
for the improved results. In 2009, the City of Missoula will continue to sample this outfall and look for patterns and
indicators as to the source of the pollutants and ways to decrease them.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 11
In addition, samples were collected as part of the Illicit Discharge Detection and Elimination Program. Section
2.3.1.3 of this report contains information related to these samples.
2.3.3 Storm Water Activities for 2009 (General Permit requirement Part IV.I.3)
The City of Missoula will continue all of its Illicit Discharge Detection and Elimination BMPs from the previous
reporting cycle. A comprehensive storm water map of the Missoula Urban Area has been created and will be
updated continuously using engineers’ as-built drawings and field verification techniques. The City of Missoula will
continue enforcing municipal water quality ordinances, as well as reviewing, combining, editing, and developing
new ordinances as necessary to prohibit illicit discharge to the maximum extent practicable. More areas will be
investigated for dry weather flows and illicit discharge. MVWQD will continue to distribute educational pamphlets
and utility stuffers for household and hazardous waste management and disposal related to water quality
protection. The City will continue implementing the extension of municipal sanitary sewer to the priority areas
identified in the Unsewered Areas Evaluation and the projects identified in the City’s Wastewater Facility Plan as
well as the City’s goals for abandoning septic systems under the VNRP. Finally, the City will continue the work to
upgrade the municipal wastewater treatment facility’s BNR system.
In 2009, the City, County, and MVWQD will review and research discharges and flows from sources listed in Parts
II.A.3.a.vi and vii of the General Permit. Sources which are found to be significant sources of storm water pollution
will be added to the plan for management and mitigation. See Appendix G for Storm Water BMP implementation
schedule. Additional testing related to the Illicit Discharge Detection and Elimination Program, as well as General
Permit Part IV – Monitoring, Recording and Reporting Requirements, will be performed. Refer to sections 2.3.1.3
and 2.3.2 of this report for more information.
2.3.4 Proposed Changes to the SWMP (General Permit requirement Part IV.I.4)
No changes to the Illicit Discharge Detection and Elimination portion of the Storm Water Management Plan are
being proposed at this time.
2.3.5 Notice of Reliance on Another Government Entity (General Permit requirement Part IV.I.5)
The City of Missoula will not be relying on any other government entity for the implementation of its Illicit
Discharge Detection and Elimination BMPs.

2.4 Construction Site Storm Water Runoff Control Measures
2.4.1 Status of Compliance with Permit Conditions (General Permit requirement Part IV.I.1)
2.4.1.1 Requirement/Minimum Measure: Develop and implement an ordinance or other regulatory
mechanism to require erosion and sediment controls, as well as sanctions to assure compliance, to the extent
allowable under state or local law.
Best Management Practice: Code enforcement
Measurable Goal: Review, combine, edit and develop ordinances as necessary to meet this requirement.
Implement enforcement of new laws and procedures immediately after adoption.
Status: The City of Missoula has numerous codes and ordinances which address water quality issues pertaining
to construction site storm water runoff control measures. Various sections of the Missoula Municipal Code dealing
with health, safety, streets, sidewalks, and public places, as well as a section of the Missoula City-County Air
Pollution Control Program have been applied to revised Administrative Rule No. 414: Construction Site Cleanup
and Right-of-Way Protection. This rule forbids any material including mud, dirt, rocks, and debris from being
tracked, dragged, or spilled from a construction site onto a public street or right-of-way. The rule also names the
construction permit holder as the party responsible for compliance and provides for No Access notices to be
posted at non-complying work sites. Finally, City of Missoula standard drawing number STD-408: Temporary
Access to Construction Sites is referenced, which outlines requirements for construction site access and drag-on
mitigation.
In addition, two chapters of the Missoula City Zoning Ordinance pertain to construction site storm water runoff
control measures. Chapter 19.71 – Grading, Drainage, and Erosion Control provides minimum standards for site
grading and the control of storm water runoff, both quality and quantity. It creates submittal and development
standards for erosion and sediment control, preservation of natural drainage systems, flood mitigation, site
grading, and protection of property for disturbed areas of greater than one acre. Chapter 19.67 – Hillside Design
Standards sets additional requirements for developments located on slopes over ten percent. Finally, chapter
15.64 of the Missoula Municipal Code establishes the requirement for acquiring a Grading Permit before
commencing grading associated with a building permit or zoning compliance permit on public or private property.
This chapter also establishes a fee structure and penalties for commencing work without a permit. Copies of all
codes and administrative rules can be found in Appendix D starting on page D-1.
2.4.1.2 Requirement/Minimum Measure: Develop and implement requirements for construction site
operators to implement appropriate erosion and sediment control BMPs.
Best Management Practice: Construction standard drawings
Measurable Goal: Develop a series of standard drawings for each of the construction best management
practices for construction. Distribute to developers and contractors throughout the Missoula urban area.
Status: Seven new construction site storm water runoff control standard drawings were created in 2005 and
2006. The drawings are required to be part of applicable City subdivision projects by Missoula City Zoning
Ordinance Chapter 19.71 – Grading, Drainage and Erosion Control. Drawings include Temporary Access to
Construction Sites, Silt Fence Installation, Post-Paving Gravel Curb Intake Filter, Pre-Paving Gravel Intake Filter,
Straw Bale Check Dams, and Sediment Control at Field Catch Basins. In the future, city personnel will evaluate
their effectiveness and revise and/or add drawings as necessary. Copies of standard drawings can be found
beginning on page D-15 of Appendix D.
2.4.1.3 Requirement/Minimum Measure: Develop and implement requirements for construction site
operators to control waste such as discarded building materials, concrete truck washout, chemicals, litter, and
sanitary waste at the construction site that may cause adverse impacts to water quality.
Best Management Practice: Construction standard drawings
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 13
Measurable Goal: Develop a series of standard drawings for each of the construction best management
practices for construction site "house keeping". Distribute to developers and contractors throughout the Missoula
urban area.
Status: Several sections of the Missoula Municipal Code address the presence of debris at construction sites.
Administrative Rule Number 414 was written to gather all pertinent sections into one central location. In addition,
authority is given to enforce ordinances and a schedule of enforcement procedures is outlined. Upon
determination of non-compliance by City inspectors, a violation notice is posted at the site, the construction permit
holder is notified, and has 48 hours to bring the site into compliance. If the site is not brought into compliance
within 48 hours, a NO ACCESS notice is posted at the site and all motorized access to the site is suspended. In
the inspectors' experiences, this has been adequate to prevent or remedy any possible situations in which storm
water may be adversely affected. A copy of the administrative rule can be found beginning on page D-1 of
Appendix D.
2.4.1.4 Requirement/Minimum Measure: Develop and implement requirements for construction site
operators to control waste such as discarded building materials, concrete truck washout, chemicals, litter, and
sanitary waste at the construction site that may cause adverse impacts to water quality.
Best Management Practice: Construction activities for Federal Aid projects
Measurable Goal: Continue meeting the requirements for construction site practices for pollution prevention
for all City Federal Aid projects.
Status: During 2008, no City Federal Aid projects were in construction.
2.4.1.5 Requirement/Minimum Measure: Develop and implement procedures for site plan review that
incorporate consideration of potential water quality impacts.
Best Management Practice: Subdivision and building permit plans review and ordinance enforcement of
control measures.
Measurable Goal: Continue the existing practice for subdivision and building permit plans review and
enforcement.
Status: In order to minimize the amount of pollutants leaving constructions sites, the City began requiring that
storm water pollution prevention plans be developed and included as part of the building and subdivision plans
review process. In areas where storm drain protection is required, but not included in the submittal, the
appropriate standard drawings are attached and required to be part of the project. Standard drawings include silt
fencing, check dams, inlet protection, and site access. Standard drawings can be found in Appendix D, starting on
page D-15. City personnel make inspections to insure that storm water pollution prevention plans are being
followed and stop work orders are issued when sites are found to be non-compliant.
In 2007, city staff distributed packets of information, including a link to a new portion of the city website, for
engineering consultants performing subdivision work in Missoula. The packets contain checklists, standard
drawings, and other information to help them prepare complete and accurate submittals for the subdivision review
and approval process. This packet is scheduled to be reviewed and updated in 2009.
2.4.1.6 Requirement/Minimum Measure: Develop and implement procedures for receipt and
consideration of information submitted by the public.
Best Management Practice: Public complaint process
Measurable Goal: Continue the existing practice whereby citizens may register a complaint regarding storm
water pollution or violations with the MVWQD. MVWQD continue investigating the complaint sites to confirm the
violation. Train additional staff to respond and enforce.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 14
Status: In 2008, the Water Quality District responded to 20 water quality complaints. Two employees of the
Water Quality District serve in an on-call position for the Environmental Health Division hazardous materials
response program. An employee of the division is on-call at all times. When dispatched by 911, employees work
to minimize the threat to the public and the environment that may be present. Vehicle accidents and hazardous
material spills are managed to reduce the potential of groundwater, surface water, soil, and air contamination.
Storm drains are of particular concern and every effort is made to prevent spills from reaching the inlet. If the spill
does reach the storm drain, Fire Department, Health Department, and Hazardous Material Team Members are
trained in the use of booms and are equipped with sorbent pads to capture as much material as possible.
The City of Missoula is in the process of acquiring citizen request software which will be capable of handling
phone calls or emails. The automated system will route requests to the appropriate personnel to ensure faster
response.
2.4.1.7 Requirement/Minimum Measure: Develop and implement procedures for site plan review that
incorporate consideration of potential water quality impacts.
Best Management Practice: Grassy swales for street drainages
Measurable Goal: Continue the installation and maintenance of grassy swale street drainages.
Status: Although no new storm water swales or retention/detention ponds were built within the city limits during
2008, the City encourages the handling of storm water on site in new subdivisions. Typically, grassy swales and
retention/detention basins which are located in the right of way are maintained by the city. Homeowners’
associations or adjacent landowners are, by city code, responsible for other structures. Formal maintenance
agreements are handled at the beginning of the subdivision process and made on a case-by-case basis.
2.4.1.8 Requirement/Minimum Measure: Develop and implement procedures for site plan review that
incorporate consideration of potential water quality impacts.
Best Management Practice: Wetlands
Measurable Goal: Continue the maintenance and preservation of existing storm water wetlands.
Status: Chapter 19.51: Riparian Resource Zoning District of the Missoula City Zoning Ordinance defines areas
of riparian resource and restricts development within those areas. A map of known Missoula riparian areas is
maintained in the Office of Planning and Grants, but additional areas may be determined by stipulations outlined
in the ordinance. Construction is permitted in areas of riparian resource only when a detailed management plan
provides for restoration and/or replacement of the riparian area so that there is no net loss of area of riparian
resource. All subdivisions within the city limits of Missoula must comply with this ordinance and compliance is
determined by the Planning Director. A copy of the Riparian Resource Zoning District ordinance can be found in
Appendix D, beginning on page D-22.
2.4.2 Results of Information Collected and Analyzed (General Permit requirement Part IV.I.2)
During 2008, no information related to Construction Site Storm Water Runoff Control Measures was collected and
analyzed.
2.4.3 Storm Water Activities for 2009 (General Permit requirement Part IV.I.3)
The City of Missoula will continue all its Construction Site Storm Water Runoff Control Measures BMPs from the
previous reporting cycle, except the creation of construction standard drawings. The drawings created will
continue to be required in project submittals and will be updated as needed. The City will continue to review,
combine, edit, and develop ordinances to require erosion and sediment controls, as well as sanctions to assure
compliance. Requirements for construction site practices for pollution prevention for all Federal Aid projects will
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 15
continue to be met. Subdivision plans will be reviewed to determine the adequacy of a storm sewer protection
measures and site inspections will confirm implementation of plans. MVWQD will continue the existing practice
whereby citizens may register a complaint regarding storm water pollution or violations. Complaints will be
investigated and a plan for mitigation will be formulated. The need for additional staff will also be considered.
Grassy swales will continue to be installed in new projects where appropriate and existing swales will continue to
be maintained. Finally, existing storm water wetlands will continue to be maintained and preserved. See Appendix
G for Storm Water BMP implementation schedule.
2.4.4 Proposed Changes to the SWMP (General Permit requirement Part IV.I.4)
No changes to the Construction Site Storm Water Runoff Control portion of the Storm Water Management Plan
are being proposed at this time.
2.4.5 Notice of Reliance on Another Government Entity (General Permit requirement Part IV.I.5)
The City of Missoula will not be relying on any other government entity for the implementation of its Construction
Site Storm Water Runoff Control BMPs.

2.5 Post-construction Storm Water Management in New Development and
Redevelopment
2.5.1 Status of Compliance with Permit Conditions (General Permit requirement Part IV.I.1)
2.5.1.1 Requirement/Minimum Measure: Develop and implement strategies that include a combination of
structural and nonstructural BMPs appropriate for the community.
Best Management Practice: Code enforcement
Measurable Goal: Review, combine, edit and develop ordinances as necessary to meet this requirement.
Implement enforcement of new laws and procedures immediately after adoption.
Status: The City currently has a zoning ordinance that addresses grading, drainage and erosion control. A
separate engineering ordinance exists which permits the requirement and enforcement of grading, drainage, and
erosion control permits. Various other ordinances and administrative rules exist, parts of which address postconstruction as well as construction issues that relate to storm water quality. The process is underway to remove
all pertinent sections from their current locations and combine them into one engineering ordinance. All issues of
storm water management in construction and post-construction will be addressed in one ordinance and will be
enforced by a single entity.
2.5.1.2 Requirement/Minimum Measure: Develop and implement an ordinance or other regulatory
mechanism to address post-construction runoff from new development and redevelopment projects to the extent
allowable under state or local law.
Best Management Practice: Code enforcement
Measurable Goal: Review, combine, edit and develop ordinances as necessary to meet this requirement.
Implement enforcement of new laws and procedures immediately after adoption.
Status: The City currently has a zoning ordinance that addresses grading, drainage and erosion control. A
separate engineering ordinance exists which permits the requirement and enforcement of grading, drainage, and
erosion control permits. Various other ordinances and administrative rules exist, parts of which address postconstruction as well as construction issues that relate to storm water quality. The process is underway to remove
all pertinent sections from their current locations and combine them into one engineering ordinance. All issues of
storm water management in construction and post-construction will be addressed in one ordinance and will be
enforced by a single entity.
2.5.1.3 Requirement/Minimum Measure: Ensure adequate long-term operation and maintenance of
BMPs.
Best Management Practice: Ownership and control of existing on-site storm water structures
Measurable Goal: Research of the status of on-site storm water structures no longer maintained by inactive
Homeowners’ Associations. Develop and implement a plan for addressing ongoing maintenance needs.
Status: City staff met to discuss this BMP and develop a plan for addressing these systems. It was determined
that a complete list of these structures does not exist, so the process of creating the list was begun by
researching easement and right-of-way locations. Storm systems that are located outside of a public right-of-way
or easement are noted as being privately maintained. Owners of these systems will be contacted and reminded of
their maintenance responsibilities and the importance of minimizing adverse impacts to water quality. As a result
of this process, one large subdivision is currently filing an amended plat to give easements to the city for
maintenance of the storm system.

2.5.2 Results of Information Collected and Analyzed (General Permit requirement Part IV.I.2)
During 2008, no information related to Post-construction Storm Water Management in New Development and
Redevelpment was collected and analyzed.
2.5.3 Storm Water Activities for 2009 (General Permit requirement Part IV.I.3)
The City of Missoula will continue to research records in order to create a complete list of private storm system
owners and annual letters will be sent reminding them of maintenance responsibilities. In addition, a new BMP will
be implemented in 2009. City personnel will develop and implement a mechanism to assure the maintenance of
future on-site storm water systems. See Appendix G for Storm Water BMP implementation schedule.
2.5.4 Proposed Changes to the SWMP (General Permit requirement Part IV.I.4)
No changes to the Post-construction Storm Water Management in New Development and Redevelopment portion
of the Storm Water Management Plan are being proposed at this time.
2.5.5 Notice of Reliance on Another Government Entity (General Permit requirement Part IV.I.5)
The City of Missoula will not be relying on any other government entity for the implementation of its PostConstruction Storm Water Management in New Development and Redevelopment BMPs.

2.6 Pollution Prevention and Good Housekeeping Measures for Municipal
Operations
2.6.1 Status of Compliance with Permit Conditions (General Permit requirement Part IV.I.1)
2.6.1.1 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: Annual Street Cleaning Program
Measurable Goal: Continue the (April through September) sweeping of all public streets maintained by the
City three times each.
Status: During the summer months of 2008, 7,104 residential area curbline miles, 487 commercial area curbline
miles, and 912 state route centerline and curbline miles were swept. During the course of this cleaning, 1607
loads of debris, weighing approximately 3 tons each, for a total of 4,821 tons of debris removed from city streets
and state routes.
2.6.1.2 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: City’s Winter Street Cleaning Program
Measurable Goal: Continue to annually clean all public streets maintained by the City during winter months
from November to March as temperatures rise above freezing
Status: During the winter months of 2008, 3,104 residential area curbline miles, 983 centerline and curbline
miles, and 312 traffic lane miles were swept. During the course of this cleaning, 1091 loads of debris, weighing
approximately 3 tons each, for a total of 3,273 tons of debris removed from city streets and state routes.
2.6.1.3 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: Alternative product usages in accordance with agency snow/deicing plans.
Measurable Goal: Continue using deicers that meet the City’s water quality specifications.
Status: During 2008, the City used 355,850 gallons of liquid magnesium chloride. The use of deicer in lieu of
sanding material reduces siltation in rivers and streams while still providing safe and convenient travel ways for
the public. The trade-off is that deicers contain pollutants which may eventually make their way to surface waters.
The Missoula City/County Health Department has stipulated that any deicer used within an area five miles outside
of the city limits must contain “the least amount of any constituents which are not essential to the product’s
performance and which may cause contamination of soil or water, including inert or proprietary ingredients”. The
City of Missoula has adopted this requirement in section 13.26.040 of the Missoula Municipal Code. The code
outlines the use of deicer, provides constituent limits for various pollutants, stipulates a department approval
process, sets field delivery requirements, and specifies storage and field application requirements.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 19
In 2008 the city of Missoula adopted amendments to the Water Quality Ordinance which allow the use of solid
deicers such as sodium chloride (Rock Salt). These changes do not weaken water quality parameters which were
established in the ordinance. The Water Quality District will continue monitoring effects of deicers on groundwater
and surface water.
2.6.1.4 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: Materials management
Measurable Goal: Continue tracking the results of using sanding material and liquid deicers.
Status: The EPA-approved State Implementation Plan for Missoula County designates a Required Deicing Zone
based on air quality standards. Inside this zone only liquid deicer approved by the MVWQD may be applied to
roadways when the ambient temperature in above 10°F, except under extraordinary conditions. The use of deicer
in this area has reduced the amount of particulate in the air, and has a direct affect on the amount of deposition in
rivers and streams.
2.6.1.5 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: Materials storage and recycling
Measurable Goal: Continue recycling used oil in accordance with each agency's program.
Status: At the City’s vehicle maintenance division, 2,000 to 2,500 gallons of waste oil are generated annually. All
of this oil is burned on site in a waste oil burner.
2.6.1.6 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: City Leaf Collection/Recycling Program
Measurable Goal: Continue the City’s annual November collection of all leaves raked to public curbsides for
recycling at a local composting center.
Status: Each year citizens are encouraged to rake their leaves to the street rather than sending them to the
landfill. In November, city personnel collect the leaves and take them to the local composting center. In 2008,
1,500 loads of leaves were hauled to the local composting center.
2.6.1.7 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
Missoula SWMP 2008 Annual Report

operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: MVWQD’s Stream Water Quality Monitoring
Measurable Goal: Continue the existing MVWQD stream water quality monitoring.
Status: Beginning in 2004, the Water Quality District initiated a recreational waters study examining
concentrations of enterocci and e. coli bacteria. These serve as indicators that pathogenic bacteria may be
present in the water. This monitoring continued through 2008.
2.6.1.8 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: Shop sump installation and maintenance
Measurable Goal: Continue installing and maintaining shop sumps in accordance with EPA, County, City
injection well regulations to retain solids and petroleum products on site and out of water stream.
Status: No new shop sumps have been installed in City buildings in the past year. The City’s vehicle
maintenance shop has one existing sump, which is connected to the municipal wastewater treatment plant. An
employee is assigned to inspect the sump monthly and change the oil absorbent bags quarterly or sooner if
needed. The sump collection is cleaned every two weeks.
2.6.1.9 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: City’s Open Space Preservation Program
Measurable Goal: Continue the program to acquire and preserve open space and conservation easements.
Status: In 2006, the citizens of Missoula passed a 5 million dollar open space bond. In 2008, $170,000 of that
money was used to acquire a trail easement along the three-mile proposed route from the Rocky Mountain Elk
Foundation to the Snow Bowl Road junction.
With the help of the Missoula County Weed District, the Parks Department completed a survey of the health of
grassland plant communities on all of the North Hills, Mt. Jumbo, and Mt. Sentinel. This project will direct the
management of these communities and help to more effectively reach established conservation goals. Work
continued in 2008 on an aggressive integrated noxious weed control program involving herbicide applications,
grazing, hand pulling, biocontrol insects, reseeding, and education. Following a summer burn on the face of
Mount Sentinel, private donations, grants and volunteers reseeded the area in early November.
This year the National Public Lands Day project included directing volunteers to help re-locate a portion of the
Tower Street Conservation Area river loop trail from its original location right along the eroding river bank to be
further away from the bank. Native shrubs were planted along the former trail.
Council approved a budget for drafting and adopting a Conservation Lands Management Plan in September. An
RFP was sent out in November. Work on drafting the plan will begin early next year.
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 21
An interim moratorium on all competition, special events, commercial events, and group activities/gatherings on
Conservation Lands was implemented late in 2006 to protect lands from overuse. The interim moratorium has
been an effective way to manage use on open spaces and will stay in effect until the Conservation Lands
Management Plan is adopted next year.
A pilot study was begun to gauge the amount of recreational use at main trailheads and to survey users on their
satisfaction of Mt. Sentinel, Mt. Jumbo and the North Hills. Accurate trail counts and surveys were issued by
interns throughout the summer.
We continue to gain experience with every passing year how to better manage the recreation demands and
vegetation challenges on our open space lands and balance the public demands with a program of grazing, biocontrol and spraying. In Spring of 2007, a new 6 member committee, the Conservation Lands Technical Advisory
Group, was formed to provide technical advice and information for managing Missoula’s Conservation Lands.
The group has met several times with the City's Conservation Lands Manager.
2.6.1.10 Requirement/Minimum Measure: Develop and implement an operation and maintenance
program that includes a training component and has the goal of preventing or reducing pollutant runoff from
municipal operations. Using training materials that are available from EPA, the state of Montana, or other
organizations, the program must include employee training to prevent and reduce storm water pollution from
activities such as park and open space maintenance, fleet and building maintenance, new construction and land
disturbances, and storm water system maintenance.
Best Management Practice: City/County Storm Water Infiltration Systems
Measurable Goal: Continue operating and maintaining existing storm water infiltration systems.
Status: Currently, there are 4,774 injection wells within the city limits, located on city streets and state routes. As
part of the Maintenance Management System and the Storm Water Utility, regular, preventative maintenance will
be scheduled and performed for all injection wells. At the present, however, maintenance is normally done in
response to problems with drainage. In 2008, 15 new injection wells were installed, 14 were redug and 29 were
cleaned by city personnel. In addition, 52 new injection wells were installed by contractors as part of private
subdivision projects.
2.6.1.11 Requirement/Minimum Measure: Develop and implement an operation and maintenance
program that includes a training component and has the goal of preventing or reducing pollutant runoff from
municipal operations. Using training materials that are available from EPA, the state of Montana, or other
organizations, the program must include employee training to prevent and reduce storm water pollution from
activities such as park and open space maintenance, fleet and building maintenance, new construction and land
disturbances, and storm water system maintenance.
Best Management Practice: Storm drain system cleaning
Measurable Goal: Continue cleaning the storm drain system annually.
Status: Currently, the City of Missoula cleans storm drains on an as-needed basis. With the creation of the
storm water utility, the city hopes to hire more employees and buy more equipment so that the storm drain system
can be included in a routine maintenance schedule. In 2008, 23 storm drain inlets, 21 outfalls, and approximately
1200 feet of storm pipes were cleaned.
2.6.1.12 Requirement/Minimum Measure: Develop and implement an operation and maintenance
program that includes a training component and has the goal of preventing or reducing pollutant runoff from
municipal operations. Using training materials that are available from EPA, the state of Montana, or other
organizations, the program must include employee training to prevent and reduce storm water pollution from
Missoula SWMP 2008 Annual Report
Section 2 – City of Missoula; Page 22
activities such as park and open space maintenance, fleet and building maintenance, new construction and land
disturbances, and storm water system maintenance.
Best Management Practice: Preventative maintenance scheduling and maintenance recording.
Measurable Goal: Continue the use of our asset management software to track maintenance, schedule
preventative maintenance measures, and track trends in problem areas.
Status: In order to prevent sanitary sewer back-ups and overflows, and storm drain flooding, a system has been
developed to track sewer asset maintenance. Scheduling and tracking of biannual sanitary sewer maintenance is
already being done with this system, along with recording citizen requests and non-scheduled maintenance.
Areas have been identified which require more frequent cleaning in order to avoid potentially dangerous back-up
and overflow conditions.
City personnel are currently field verifying storm water asset locations. Some storm sewer maintenance is being
entered for some asset types, and maintenance schedules are being developed. The storm sewer tracking
capability will be fully functional by the time the storm water utility has been created.
2.6.1.13 Requirement/Minimum Measure: Develop and implement an operation and maintenance
program that includes a training component and has the goal of preventing or reducing pollutant runoff from
municipal operations. Using training materials that are available from EPA, the state of Montana, or other
organizations, the program must include employee training to prevent and reduce storm water pollution from
activities such as park and open space maintenance, fleet and building maintenance, new construction and land
disturbances, and storm water system maintenance.
Best Management Practice: Grassy swale maintenance
Measurable Goal: Continue the maintenance and preservation of existing grassy swales for street drainage.
Status: Typically, grassy swales and retention/detention basins which are located in the right of way are
maintained by the city. A large swale which is located in a City park and is part of the South Missoula Storm Drain
System was mowed six times during the summer of 2008. Homeowners’ associations or adjacent landowners are,
by City code, responsible for other structures. Formal maintenance agreements are handled at the beginning of
the subdivision process and made on a case-by-case basis.
2.6.2 Results of Information Collected and Analyzed (General Permit requirement Part IV.I.2)
The storm water sample taken during 2007 at Missoula's commercial/industrial sampling site showed
exceedances of median concentrations for total suspended solids, chemical oxygen demand, total phosphorus,
total nitrogen, and zinc. In addition, the standard value for oil and grease was exceeded. Samples taken during
2008 (see pages A-11 and A-12) were considerably cleaner than the sample taken during the previous year and it
is thought that good housekeeping measures such as additional street sweeping as well as the cleaning of the
upstream detention basin may have contributed.
2.6.3 Storm Water Activities for 2009 (General Permit requirement Part IV.I.3)
The City of Missoula will continue all of its Pollution Prevention and Good Housekeeping Measures for Municipal
Operations BMPs from the previous reporting cycle. The City will continue its annual street cleaning program,
winter street cleaning program, use of deicers, and recycling of used oil. The tracking of deicer use versus
amount of sand applied to streets will also continue. In November, all leaves that have been raked into the street
will be collected and composted. MVWQD will continue its stream water quality monitoring. City agencies will
continue installing and maintaining shop sumps in accordance with EPA, County, and City injection well
regulations to retain solids and petroleum products on site and out of water streams. The City of Missoula will
have the balance of 5 million dollars to continue spending on open space land acquisition and will continue to
receive training in appropriate BMPs. Continue operating and maintaining existing storm water infiltration
systems. Continue cleaning storm drain systems annually. Continue the use of our asset management software to

Operations
5.6.1 Status of Compliance with Permit Conditions (General Permit requirement Part IV.I.1)
5.6.1.1 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: Annual Street Cleaning Program
Measurable Goal: Continue the sweeping of all UM streets and parking lots on an as-needed basis throughout
the year.
Status: UM expended 280 total hours on both the small and large sweepers, sweeping streets, sidewalks and
parking lots.
5.6.1.2 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
and open space maintenance, fleet and building maintenance, new construction and land disturbances, and storm
water system maintenance.
Best Management Practice: Materials storage and recycling
Measurable Goal: Continue recycling used oil in accordance with each agency's program.
Status: The motor pool recycled 815 gallons of used oil.
5.6.1.3 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park

water system maintenance.
Best Management Practice: Monitor and prevent fuel site releases
Measurable Goal: Continue monitoring practices for fuel release detection at agency fueling sites.
Status: The University Motor Pool has many ways to prevent the spilling of fuel from the fueling facility. 1) The
fueling system is programmed with a portion of the capacity of each vehicle’s tank and the pump automatically
stops once that amount is dispensed. 2) The fueling facility has break away shut off valves on the hoses to stop
the fuel flow if the hose is torn off. 3) The pumps automatically shut off after 1 minute of no use. 4) There is an
emergency shut off near the pumps that shuts all power off. 5) There is not storm sewer in the immediate vicinity
of the fueling facility.
5.6.1.4 Requirement/Minimum Measure: Develop and implement an operation and maintenance program
that includes a training component and has the goal of preventing or reducing pollutant runoff from municipal
operations. Using training materials that are available from EPA, the state of Montana, or other organizations, the
program must include employee training to prevent and reduce storm water pollution from activities such as park
