Air Quality Control - Visible Emissions, Dust, and Odor
Air Quality Control – appropriate actions should be taken to minimize the amount of air pollution created by construction operations. All operations should be conducted in a manner to avoid creating a nuisance.

Visible Emissions - all project sites should minimize the amount of visible emissions. Equipment should be maintained and operated to limit vehicle exhaust emissions. All forms of visible emissions must be controlled.

Dust - Dust shall be kept down at all times, including non-working hours. Construction activity should be conducted to minimize the formation of dust. This may require equipment limitations, covering soil piles, utilizing dust suppressors, etc.

Odor - Work being performed on construction sites may generate odors not normally encountered in everyday work areas. All products or processes that could create odors or smoke should be reviewed in advance by OSEH for use in occupied buildings. Any suspicious odors should be reported to OSEH at (734) 763-4568.

Refrigerants
To comply with EPA regulations, outside contractors must contact Plant Operations Air Conditioning Shop if equipment containing chlorofluorcarbons (CFCs), or hydrochlorofluorcarbons (HCFCs) is to be installed or removed.

The Air Conditioning Shop has developed procedures and a database for tracking refrigerants. Any contractor installing or removing refrigerants must complete the Contractor Refrigerant Reporting Form which is available at:

http://www.plant.bf.umich.edu/utilities/operations-engineering/CFC_Form.pdf

If you are removing or installing equipment containing any of these refrigerants, please contact the Plant Operations Air Conditioning Shop immediately at (734) 647-2059.

Oil & Chemical Storage
Small Containers
Containers for oil and chemical storage (bottles, jugs, drums, vials, boxes, etc.) must be:

• In good condition (no cracks, leaks, rust, etc.)
• Placed in secondary containment
• Compatible with the chemical
• Labeled with the “Chemical Name” or each constituent in the container
• Kept CLOSED unless actively removing chemicals. Funnels must be removed immediately after use and the container lid must be closed and sealed.
• Incompatible chemicals should be segregated.
• All containers should be protected from the elements.
• All containers should be secured to prevent theft or vandalism.

Bulk Containers

• The University of Michigan follows the Spill Prevention Control and Countermeasure (SPCC) Plan and Michigan Part 5 Rules ---- Spillage of Oil and Polluting Materials to control chemical bulk storage. Contractors must follow these regulations.
• Secondary containment is required for all oil and chemical bulk storage containers. The secondary containment system must hold 100% of the largest container or 10% of the total volume of all the containers in the system, whichever is larger.
• Catchment must be in place while unloading and loading from a tanker truck to an aboveground or underground storage tank. The catchment must hold the capacity of the largest inner single compartment of the delivery truck.
• All oil containers 55 gallons or greater must be inspected monthly for leaks or spills.

Storm Water
Never pour anything down drains located outside of a facility. The only materials permitted to enter the storm water drainage system are storm water runoff and potable water (no additives, soap, chemicals, sediment, etc.) from a few very specific sources. Contact OSEH at (734) 936-1920 with any questions regarding discharges into the storm water drainage system.

Protect all storm drains from unauthorized discharges such as construction site wastes which includes concrete washout, sediment, paint, gas, oil, antifreeze, maintenance and cleaning wastes.

Report accidental spills or dumping
Promptly report any suspected spills or illicit discharges into the storm water drainage system to DPS at (734) 763-1131 for cleanup.

Soil Erosion and Sedimentation Control (SESC)
As an Authorized Public Agency, the University of Michigan (statewide) has established SESC Procedures to prevent off-site soil erosion and sedimentation to Waters of the State, storm drains and adjacent properties.

All construction operations/projects involving earth work are required to use SESC measures and best management practices to prevent sediment from entering the storm water drainage system. For sites larger than 1 acre or within 500 feet of Waters of the State, a site specific SESC Plan must be designed, approved by OSEH, and retained on-site.

• Evaluate the site to determine the location of nearby storm drains, including along expected truck routes. If there is potential for sediment to enter storm drains, install inlet protection such as silt sacks or fabric filter. Be sure to protect the backflow opening of curb drains and wrap grates for ease of maintenance.
• Use perimeter barriers such as vegetative filter strips or silt to control sediment from leaving the site. Silt fence must be installed correctly and trenched.
• Place stockpiles away from storm drains. If stockpiles must remain on-site overnight, cover the pile with water repellent material or apply other erosion control methods. Keep as few stockpiles as possible during the course of the project.
• Guard exposed soils and stockpiles against wind erosion by wetting the site during dry, windy conditions.
• Sweep trackout on a daily basis and more frequently as needed. Non-University streets cannot show any signs of trackout. To reduce trackout, install an entrance anti-tracking pad with a minimum of 50 feet in length. A geotextile filter fabric should be placed under 6 inches of limestone aggregate.
• Grade and stabilize the work area with vegetation, mulch, erosion blankets or hardscaping immediately after project completion.
• Remove all temporary SESC measures when site work is complete and vegetation is established.

SESC measures must be maintained daily. Weekly and after-storm inspections are performed by OSEH. Any recommendations identified must be corrected within 5 days, or immediately if Waters of the State are impacted.

For more information on the University’s SESC Procedures, visit our website at
www.oseh.umich.edu/stormwater/emsec.html or contact OSEH at 734)936-1920.

Concrete Washout
Concrete washout typically has a high pH, can be harmful to the environment, and cannot be disposed of in a storm or sanitary drain. Proper disposal and washout practices should be implemented. Wash concrete trucks in designated areas or offsite.

Designated areas should:

• Be labeled.
• Be a pit to prevent runoff.
• Be approx. 50 ft away from storm drains, bodies of water, and ditches.
• Have some type of liner to prevent seepage.
• Have some type of barrier.

Alternative: Set up a concrete box. If only a small amount of concrete washing is to occur, line a roll-off box.

Once concrete is washed out into the designated area and allowed to harden, it should be broken up and properly disposed on a regular basis. Washout facilities must be cleaned, or new facilities must be constructed and ready for use once the washout is 75% full.

For more information, contact OSEH at (734) 936-1920.

Exterior Cleaning and Power Washing
Contact OSEH at (734) 936-1920 before commencing any outdoor cleaning activities or power washing (including masonry, stone, and brick cleaning). Be aware of the impacts that any dislodged pollutants or cleaning products might have on groundwater and surface waters. Avoid using acids and other toxic cleaners, and whenever possible, use plain water. If this is not possible, use a less toxic cleaner.

Washing with water
If only water is being used to clean a non-polluted surface ensure:

• All storm drains are blocked
• Filter fabric or silt sacks are installed to filter solids from runoff.
• Fabric or sacks are emptied of collected sediment as needed.

When work is complete, sediment and other solids that remain on the ground should be cleaned up immediately to prevent them from being washed into the storm water system. It is important to limit sediment from entering catch basins because it can clog lines and lead to localized flooding and high maintenance costs.

Washing with water and detergents or chemical applications
If water is not sufficient for cleaning, all chemical cleaning applications must be reviewed and authorized by OSEH for proper waste disposal requirements. The Michigan Department of Environmental Quality Waste Management Guidance for Mobile Power Washing outlines potential disposal options. If the wash water does not meet the criteria for these disposal options, then it must be collected and tested to determine if it is a liquid industrial waste or if it is considered a hazardous waste.

On campus there are two options that are recommended for managing wastes generated by outdoor washing/cleaning activities:

1. Collect all wash water into appropriate, chemical compatible containers for proper disposal.
• Containers must be labeled with appropriate contact information, accumulation start date and the contents of the container, including chemical constituents in the waste. Containers and labels may be acquired from OSEH at (734) 763-4568.
• Sample and analyze the waste for constituents of concern and determine proper waste management and disposal. Contact OSEH at (734) 763-4568 to provide sampling, analysis, and subsequent waste management options. Note: Analysis will need to be performed on a representative sample of the waste and may take up to 10 business days.
• All liquid industrial waste or hazardous waste must be disposed through an OSEH approved contractor. If the wash water meets the requirements for disposal to the sanitary sewer, OSEH will make the proper arrangements with the City of Ann Arbor WWTP.
• If the material is a liquid industrial waste or hazardous waste, all manifests must be reviewed and signed by an authorized OSEH representative. Complete a draft manifest and fax it to OSEH at (734) 763-4600. The manifest will be reviewed and any correction or additional information will be itemized and returned to you for completion of the final manifest. Once the manifest content is approved, contact OSEH to schedule an authorized staff member to sign the manifest during waste pickup.
2. Obtain approval from the Michigan Department of Environmental Quality (MDEQ) to discharge to the ground by “authorization by notification.” The authorization letter from MDEQ is good for 5 years. For the MDEQ application, rules, and technical guidance, visit the MDEQ Groundwater Discharge web page. This approval has been obtained for UM employees working on campus. This approval does not cover contractors. Contact OSEH to review the environmental requirements for your specific operation. Contractors must obtain approval as a mobile power washer which covers exterior cleaning activities throughout the State of Michigan. Please note that this approval applies only to discharge to the ground. Under this approval, discharge to the sanitary sewer or storm water drainage system is prohibited.

Contact OSEH at (734) 936-1920 for assistance or additional information on these requirements.

Other Cleaning Alternatives
Instead of washing with water and chemical applications, determine what alternative dry methods are available. Use absorbents such as sawdust or vermiculite, brooms or wire brushes to clean pavement, building and equipment as much as possible. Mechanically remove and collect loose debris.

Waste Disposal
Construction/ Demolition Debris Disposal

• Items that can be salvaged or recycled at contractor’s discretion:
• Carpet
• Lumber
• Steel and scrap metal
• Porcelain and ceramics
• Acoustic ceiling tiles
• Glass
• Concrete and brick
• Excess latex paint
• Items covered under contract specification sections. Refer to those sections for specific waste handling, if applicable:
• Asbestos Containing Materials
• Lead Materials
• PCB Waste
• Fluorescent Light Bulbs and Ballasts (Electrical)
• Regulated Construction Waste (batteries, smoke detectors, mercury-containing devices, etc.)

Wastes that cannot be salvaged or recycled should be managed as regular construction debris; however, some wastes require special handling.

Hazardous and Special Waste Disposal

• Materials that may require special handling and/or are characterized as hazardous waste or special industrial waste:
• Paint and used brushes
• Thinners and solvents
• Used oil
• Antifreeze
• Rags contaminated with any of these materials
• Excess latex paint (Note: Solidify for disposal with other construction materials.)
• Oil based paints
• Other suspected chemicals may be regulated as a hazardous waste or special industrial waste
• All waste containers must be:
• In good condition (no cracks, leaks, rust, etc.)
• Compatible with the waste
• Labeled with ALL the following:
• “Hazardous Waste”
• The RCRA/ MI Act 451 Waste Code (chemical name that identifies each constituent in the container)
• The Accumulation Start Date – the date the first drop of waste was placed in the container. (NOTE: The container cannot be kept for more than 90 days.)

Proper management of hazardous chemical, biological, radioactive, and non-classified waste must comply with state and federal regulations and promote environmental stewardship. Contact OSEH at (734) 763-4568 with any questions regarding hazardous waste management, manifesting and disposal. All hazardous waste manifests and disposal options must be approved by OSEH.

Waste Water
Waste water generated from a project may be managed in several different ways, depending on generation and chemical constituents.

Potential waste water streams:

• Chiller water
• Cleaning solutions
• Flushing solutions
• Exterior building wash water
• Window cleaning wash water
• Latex paint waste water

NOTE: Some waste water generated from a project may be suitable for disposal to the sanitary sewer. The City of Ann Arbor Sewage and Sewage Disposal Ordinance outlines what wastes may be suitable for disposal to the sanitary sewer. All communications to the City of Ann Arbor Waste Water Treatment Plant should be handled by OSEH at (734) 936-1920.

Refer to the Exterior Cleaning section of this document for guidelines on proper management of wash water from exterior cleaning operations.

Contact OSEH at (734) 936-1920 for a review of waste water disposal issues for your project.

Report accidental spills or dumping
Never pour anything down drains located outside. Promptly report any discharges or dumping onto the ground, into sewers, etc. to DPS at (734) 763-1131 for cleanup.

Suspect Contaminated Soil, Groundwater, or Unknown Material

• During work activities, if suspect contaminated soil, groundwater, or other unidentified material is encountered, please contact your Construction Management Representative.
• Suspect contaminated soil may exhibit chemical or unusual odors, staining, unusual coloring, and may contain man-made debris.
• Suspect groundwater may exhibit chemical or unusual odors, unusual coloring, and/or a sheen.
• The Construction Management Representative shall immediately contact OSEH at (734) 763-4568.
• All excavation, dewatering, transport, or disturbance of the suspect material shall immediately stop, but not before the site is stabilized (i.e., bracing and shoring), OSEH will immediately be contacted to investigate the situation.
• If the inspection indicates no special handling or disposal protocols are required, resume work activities upon OSEH notification.
• If special handling or disposal protocols are required, OSEH will notify the Construction Management Representative with pertinent instructions.
