THE UNIVERSITY OF MICHIGAN – FLINT Environmental Compliance with… 1- New NPDES Storm Water Management Permits 2- SPCC & Michigan PART 5 Requirements 3- Environmental Due Care Env., Health and Safety & Facilities Management March 2010 Portions of Training materials adopted from UM OSEH Storm Water Mgt. is strictly regulated… it dates back several decades Federal Clean Water Act of 1972 CWA amendments of 1987 required permits for storm water discharge (Phase I and II). Federal Phase I SW Regulations began 1990 Industrial Sites: certified ISW operator Construction sites over 5 acres: requires SESC plans, weekly inspections by certified CSW operator Municipalities over 100,000: public education, illicit connections, maximum extent practicable measures Federal Phase II SW Regulations (1999) Industrial Sites: about the same as above, certified operator Construction sites 1-5 acres: w/ certified operator Municipalities under 100,000: Three permit options under Phase II: General permit, Individual permit, or Modification –MS4 UM ‘s renewed 2009 Combined Permit (AA, Dearborn & Flint) UM-Flint’s pool discharge permit Michigan Env. Protection Regulations Part 31, Water Resources Protection of NRP Act of 1994 Empowers Director of MDEQ to protect & conserve water resources… adopt, establish/enforce rules, penalties Prohibits pollution of state’s waters, etc. Part 91, Soil Erosion and Sedimentation Control of NRP Act of 1994 Requires control of soil erosion and sedimentation Permits, SESC plans for “earth Changes” of one acre or more or any “earth change” within 500 feet of river, lake, stream… Regulated by local, county or state Authorized Public Agency (APA) Part 301, Inland Lakes and Streams (1994) Regulates activities in lakes/streams, requires permit, i.e dredging, SESC, etc Part 303 Wetland Protection Act (1994) Protected like other surface water from SW contamination Part 17, Michigan Environmental Protection Act Provides for citizens to bring legal action “for conduct that may pollute, impair, or destroy the air, water, or natural resources.” Part 305 Natural Rivers Act (1970) Regultes activities w/in 400 ft of “Natural River District” … building, removal of vegitation, land alteration, bridge work… The “Big Picture” of Storm Water Discharges So what does this mean for UM-Flint? * UM-Flint is in the Flint River Watershed * Stop pollutants from entering the Flint River… through storm drains or by runoff directly to the river or ditches that lead to the river * Report illicit discharges & spills immediately to Public Safety/EHS * Always use best management practices at work, home and play * Attend trainings and workshops * Encourage others to do the right thing UM Ann Arbor has been operating under a “Voluntary” NPDES permit dating back to the Federal Phase I (1990’s) Flint and Dearborn were required to comply w/ SW Regulations under Phase II by March 2003. UM has petitioned MDEQ to include the Flint and Dearborn campuses into the existing permit… all under “The Regents of UM”. NOW, All THREE campuses fall under one MDEQ (new renamed MDNRE) permit. Increased documentation, inspections, education/training for employees, contractors and the general public. UM Storm Water Permit Requirements (NPDES Permit # MIS049000) Authorized Discharges - ONLY STORM WATER! Some minor exceptions… irrigation, uncontaminated groundwater, potable water, foundation drains, lawn water runoff, water line flushing and discharge of potable water, noncommercial car washing, residual street wash waters, flows from emergency fire fighting activities.

Spill Prevention Control and Countermeasure Plan (SPCC) Plan required by the United States Environmental Protection Agency under 40 CFR part 112 UMF SPCC Plan - 2003, rev 2006, rev 2009 PURPOSE: Plan outlines measures to prevent the discharge of OIL into the navigable waters. Spill Prevention Control and Countermeasure Plan (SPCC) Definition of OIL – oil of any kind or in any form, including but not limited to: Petroleum fuel oil sludge oil refuse kitchen grease animal fats oil mixed with wastes Spill Prevention Control and Countermeasure Plan (SPCC) Who is Required to Implement a SPCC Plan? A facility that exceeds: Total UNDERGROUND storage capacity greater than 42,000 gallons or An aggregate or combined aboveground storage capacity greater than 1,320 gallons, and Reasonable expectation that a discharge could reach a navigable waterway. Spill Prevention Control and Countermeasure Plan (SPCC) What is required of a Facility under the regulations? 1. A written plan certified by a Professional Engineer (PE) every 3 years. 2. Oil storage management and control 3. U-M Facility Personnel involvement Routine inspections Spill prevention and spill control Best Management Practices Record keeping SPCC Plan Requirements Written Plan State general information of the facility Facility Response Coordinator and Alternate Name of facility, address, phone numbers Nearby surface water body/ distance Facility Description Description of campus Facility drainage areas (storm water discharges to streams, creeks) Oil storage, distribution and use (explain type of containers) Spill history Potential releases and prevention controls Loading and unloading operations SPCC Plan Requirements Written Plan - Continued Spill Response Plan UMF has a effective ERP that serves as a guidance document. The ERP incorporates the criteria for oil removal contingency plans specified in 40 CFR Part 109. Approximately 30 U-M personnel have completed the 32-hour Hazardous Waste Operations Emergency Response Technician/ Incident Command Level training. Remedial action – Plan distinguishes between incidental spill nad emergency release ERP available online at www.umflint.edu/ehs/ Inspection schedule –(monthly, quarterly & annually) Describe the routine inspection schedule Current schedule was approved by the EPA in 2001 SPCC Plan Requirements Written Plan - Continued Personnel training Oil handling personnel trained in Become familiar with laws and regulations regarding spills, releases, and pollution control Contents of the UMF SPCC plan (rev 2009) Operation and maintenance of equipment to prevent discharges including performing the routine inspections. SPCC Plan Requirements Oil Storage Management and Control Oil storage management and control as stated in the regulations and in the written plan. Lighting Security Secondary Containment Catchment during loading and unloading fuel SPCC Plan Requirements Oil Storage Management and Control Lighting Per the EPA, as long as the oil storage area is accessible with a flashlight, this is considered adequate lighting. Security To assist in preventing spill or release from being caused by accidental or unknown entry or vandalism. Fenced area Padlocks Security guards Stored inside building SPCC Plan Requirements Oil Storage Management and Control Secondary Containment Secondary containment is required for OIL containers with the capacity of 55 gallons or greater and is to prevent any spills from any leaking or damaged containers. The secondary containment must have the capacity to hold the volume of the largest container or 10% of the combined containers, whichever larger. If room has no floor drains, then the room itself may be considered sufficient secondary containment. If the room is considered the secondary containment ensure there is a lip at the door so no liquids can exit the room in the event of a leak. Secondary Containment SPCC Plan Requirements Oil Storage Management and Control Fuel Catchment The SPCC plan requires catchment to be in place during refueling operations from a tanker truck to an aboveground or underground storage tank that will hold the capacity of the largest inner single compartment of the delivery truck. Fuel Catchment SPCC Plan Requirements UM-Flint Personnel Involvement Container Inspections Monthly and quarterly inspections Trained oil-handling personnel should perform the routine inspections. OSEH & EHS provides assistance to the Facility Managers and Supervisors by explaining the environmental regulatory requirement and therefore relies on the FM and Supervisors to ensure the routine inspections are being performed on time.

Young’s Environmental DPS & EHS Supervisor Director Due Care Regulatory Requirements: ENVIRONMENTAL DUE CARE AT UM-FLINT Due Care Regulatory Requirements: UM-Flint is subject to due care obligations for all activities that may disturb the soil/earth i.e. construction, maintenance, subsurface activities at the following properties: WSW Building and surrounding areas including former Horse Barn Former Perry Printing Site Parking Lot A and all surrounding areas (CE/MGP) Hubbard Compound Northbank Center, NBC Parking Ramp and surrounding areas Proposed Student Hosing Site and surrounding areas The properties are classified as a “facility” (Part 201 of Act 451) because contamination has been detected in soil and/or groundwater at concentrations exceeding generic residential cleanup criteria. UM and its contractors have legally enforceable responsibilities for ensuring that: Its actions do not exacerbate existing contamination The intended use of the property will not result in unacceptable exposures to hazardous substances It takes reasonable precautions with regard to acts or omissions of third parties. These requirements are a result of previous existing environmental site conditions that existed prior to UM acquiring the property. Due Care Regulatory Requirements: PERRY WSW NBC CE MGP CEP USTs STUDENT HOUSING Due Care Regulatory Requirements: Notification to adjacent property owners, utility workers, contractors, state and local agencies. Develop and implement property specific Due Care Plans for the contaminants found in the soil or groundwater at that location.

Plans must be approved before any earth change activities begin (demolition, grading, clearing, tree removal, etc.). SESC plans are not required for project sites <1 acre or greater than 500 feet from water bodies (Flint River) but notification to EHS must be made prior to beginning and most importantly, all SESC regulatory requirements and protective measures must be followed, no matter the size of the project.. SESC Exemptions Earth disturbances that are completed/closed within 24 hours Earth disturbances that are less than 225 sq. ft. (otherwise approx. 15’ X 15’ area) Both exemptions are important to the Flint Campus because the majority of our earth disturbances will be simple landscaping, tree planting, sidewalk install/repair, or utility related projects that would be either completed w/in 24 hours or less than the 225 sq.ft exemption. Project Managers must evaluate All activities employ the appropriate Best Management Practices or BMPs to protect the river and “Waters of the State”… storm drains. Submit SESC PlanS to EHS… Project managers must compile/forward four (4) completed copies of SESC plans for review/approval. One copy to EHS Department (204 UPAV) Two copies to UM OSEH-EM Environmental Specialist / SESC Inspector Occupational Safety & Environmental Health - University of Michigan 1239 Kipke Drive , Ann Arbor, MI 48109-1010 Please allow 45 days for review and comments on plans. After EHS, OSEH-EM and University Planning have completed their review UM OSEH-EM will issue final approval of SESC plans for Flint projects >1 acre and/or within 500 feet of river. Approved plans will be stamped accordingly, one set will be retained by OSEH-EM and one set will be kept at the site. Weekly inspections and inspections after significant rain events for all sites involving earth activities must be conducted & documented. For large projects, inspections may be contracted out with the approval/coordination of EHS/OSEH. This could be an additional cost to the project. 12 Components of SESC Plans DESIGN DEVELOPMENT REQUIREMENTS Scaled Map including: 1. Legal description 2. Site location sketch 3.
