CITY OF ANTIOCH
2007/2008 Annual Report Summary
The following highlights major Clean Water program accomplishments carried out in Fiscal
Year 2007/008
NEW DEVELOPMENT AND CONSTRUCTION CONTROLS:
New development and redevelopment projects are evaluated to meet established
municipal stormwater ordinances and policies, as well as those by the County, State,
and Federal jurisdictions. The City Engineer has the authority, under City ordinance, to
require the developer/property owner to obtain coverage under the RWQCB’s General
Construction permit and submit a SWPPP.
A total of 59 construction site inspections were performed during 2007/2008. That is a
decrease of 46% from the previous year. That decrease may be attributed to the total
number of active and inactive construction sites (12). The City of Antioch continues to
utilize California Storm Water Best Management Practice Construction Activity
Handbook for review of erosion control plans and erosion control installations. City
Public Works Inspectors ensure all projects are in compliance with erosion control
standards during the entire year with extra scrutiny applied during the rainy season.
"Blueprint for a Clean Bay" is distributed at the building permit counter for citizens and
contractors who are obtaining building permits along with “Pollution Prevention – It’s
Part of the Plan”.
Although the City of Antioch is not under the jurisdiction of the SFRWQCB, the City has
implemented C.3 – New Development and Redevelopment Provisions. By being an
active participant in the C.3 process, the City of Antioch anticipates an efficient
transition when the CVRWQCB formally adopts similar new development and
redevelopment provisions in the future. Three (3) projects installed stormwater
treatment facilities this past year and, since the implementation of C.3 regulations, 19
projects are in various phases of application, review, construction, or already
completed.
PUBLIC EDUCATION AND INDUSTRIAL OUTREACH:
The City of Antioch performed PEIO at a total of 9 community events, special
engagements, and workshops. Various education and promotional items were
distributed at those events.
Developers are responsible for marking catch basins within their projects. When
stencils have worn off, Public Works personnel replace them. The City has redesigned
the stencil and is using a new “NO DUMPING – DRAINS TO RIVER” button. This
button measures approximately 3 ¾ inches in diameter and can be applied with epoxy.
The epoxy helps installation and removal as compared with the previous thermoplastic
stencil. City crews concluded the button replacement program the previous reporting
year (2005-06). No buttons were installed by City crews this past year.
On Coastal Clean-up Day this past year, 175 citizens picked up approximately 7,000
lbs. of trash over 3.5 miles along creeks and the San Joaquin River area. The City of
Antioch hosted 4 compost workshops. The compost workshops teach people how to
compost their yard waste and organic debris into beneficial mulch.
This year marked the fourth year of offering the Kids for the Bay’s Watershed Action
Program (KftB) to Antioch schools. To date, 7 teachers at two elementary schools have
gone through the program. Each teacher and the participating school’s principals must
sign an agreement committing to continuing the curriculum in future years. The training
consists of 3 classroom workshops, an action project and a field trip. Students learn
the concept of a watershed and how local bodies of water are connected to each other
and the storm drain system.
The City has a webpage dedicated to NPDES and other related environmental issues
and updates and information are sent to residents as an insert in their water bills.
MUNICIPAL MAINTENANCE:
This year 10,670 curb miles of City streets were swept. As a result of the sweeping, an
estimated 2,870 cubic yards of debris was removed from the City streets. The City also
cleaned 832 catch basins. As a result of the cleaning, an estimated 1,610 cubic yards
of material was removed from all publicly owned storm system infrastructure. The
following is the estimated amount of pollutants removed for street sweeping and storm
drain cleaning combined: copper: 452 lbs., lead: 336 lbs., nickel: 108 lbs., zinc: 1,205
lbs., total petroleum hydrocarbons: 11,112 lbs., and oil & grease: 24,267 lbs.
To control algal blooms within the Antioch Municipal Reservoir, the City of Antioch uses
a copper sulfate algaecide. However, as part of an IPM strategy, three (3) Solar Bees
were installed in FY 2006-07 which has significantly reduced copper sulfate usage. The
Solar Bees are solar powered and circulate water throughout the reservoir which
inhibits algae growth. The City of Antioch has coverage under the General NPDES
permit for the Application of Aquatic Pesticides and is part of the Contra Costa Regional
Pesticide Monitoring Group. The City does not use any pesticides containing diazinon.
As an alternative to using pesticides, approximately 40,000 ladybugs were released at
various park facilities to control aphid populations. In addition, when practicable, bait
and trap methods are used rather than conventional spray applications.
INSPECTION ACTIVITIES:
2007/2008 marks the fifth year of a partnership with Delta Diablo Sanitation District
(DDSD) to perform storm water inspection of routine and priority facilities as well as
call-outs for IDCA. Thirty-seven (37) restaurants, 3 permitted industrial facilities; 2 auto
body shops; 2 car washes; 1 car rental; 1 vehicle service station; and 1 residence were
inspected in Antioch this past year. A total of two (2) enforcement actions were taken
during 2007-2008.
Both enforcement actions were WN/PENs.
Clean Water
information is distributed during the inspections and questions answered about how to
run an environmentally clean business. An average of 4 informational items were
provided per inspection this past year. Inspection data is maintained in electronic format
and can be attached to a City map using a Geographical Information System. This
geographical information allows us to more easily track illegal discharges, target areas
for increased inspections, and concentrate on sensitive areas.
ILLICIT DISCHARGE CONTROL ACTIVITIES:
This past year, field investigators responded to 3 illicit discharge callouts. When
resolving investigations, violators are educated on proper disposal of pollutants and
required to perform clean-up. This past year, the HHW facility, located at the Delta
Diablo Sanitation District, collected an estimated total of 4,242 gallons of motor oil;
11,694 gallons of paint; 1,532 gallons of pesticides; and 167,746 lbs of
miscellaneous/non-recyclable wastes. Reporting year 2007-08 marks the first year of
e-waste collection at the HHW facility. A total of approximately 71,820 lbs of e-waste
was collected from Antioch residents.
No administrative citations were issued this past year. Citations carry fines and
corrective action.
The residential recycling program, initiated in November 2005, continues to be
successful. Residents place all their recyclables in a separate wheeled cart with a
closed lid. Street litter, especially on windy and/or stormy days, appears to have been
reduced from previous years when residents used open bins for curbside recycling.
The City continues proactive enforcement of mandatory garbage service. The intention
is to decrease the number or households without service which could potentially reduce
the amount of illegal dumping and litter that enters the MS4 throughout the City of
Antioch.
WATERSHED MANAGEMENT ACTIVITIES:
Geographical Information System (GIS) themes/layers continue to be updated to help
all department and division managers in Antioch. Antioch now has 3 full-time GIS
specialists and a GIS Manager. Data from the continuing storm sewer updates will also
contribute to this effort as well as the implementation of C.3 regulations.
