Environmental Mitigation requirements may include, but are not limited to, procedures and standards to control.
    1. Dust Control and Fugitive Emissions
      1. Construction project activity shall not cause or permit the emission of any particular matter at sufficient duration or quantity as to create a nuisance or observable deposition upon real property of another person.
      2. Reasonable precautions to control particulate emissions can include but are not limited to:
        1. Use of water or chemicals for control of dust during demolition of structures, construction, or during grading of roads or clearing of land.
        2. Covering at all times when in motion, open bodied trucks transporting materials likely to become airborne.
        3. Full or partial enclosure of stockpiled materials.
        4. Dirt or debris spilled onto paved surfaces should be swept up immediately to reduce re-suspension of particulate matter caused by vehicle movement.
    2. Odors
      1. Work that causes excessive odors shall be performed only after coordination with the OSU Project Manager. Filtering of air intakes may be needed to prevent odors and vapors from entering buildings.
      2. In cases where unavoidable odors will be produced, Contractor shall provide seven (7) business days advance notice to the OSU Project Manager in order that adequate notice can be forwarded to building occupants. Work stoppage may occur if advance notification has not been coordinated or odors and vapors from the work are found to generate complaints from building occupants.
    3. Protection of Existing Air Handling Systems
      1. Contractor shall be responsible for protection of the cleanliness of existing air handling systems at all times. This protection may include as needed:
      2. During site work or building demolition, pre-filters shall be provided and maintained on all building outside air intakes and adjacent neighboring buildings at all times throughout the construction duration.
      3. During any interior work that may create dust in the interior space and adjacent corridor/hallways, air filters shall be provided and maintained on all affected air return and exhaust grilles. Where air flow in or out of the space is not required, all air duct openings shall be temporarily sealed off with a suitable covering.
      4. Upon completion of all Work affecting existing air handling systems, the Contractor shall remove all temporary filters, covers and associated parts and restore the system to its original operating condition unless otherwise stated elsewhere in the Contract Documents.
    4. Ventilation during Painting or Other Finish Work
      1. The room/space shall be supplied with 100 percent outside air during painting and for a period of 72 hours following completion of painting.
        1. The air leaving the room/space shall be exhausted only to the outside, with no re-entrainment to any occupied spaces during painting and for a period of 72 hours following completion of painting.
    5. Construction and Maintenance Isolation Requirements
      1. All construction, maintenance, and remodeling activities, regardless of size or scope, must be fenced, barricaded, or otherwise isolated to restrict entrance and to ensure the safety of those in the general area.
      2. The contractor will provide all barricading, isolation, and fencing material. The contractor will also provide all appropriate warning and detour signs when sidewalks, exits, or roads are closed.
      3. The contractor shall submit the OSU Construction & Maintenance Safety Form and OSU Site Safety Plan to the OSU Project Manager at least one week prior to commencing work. Both forms are accessible on the OSU EH&S website under Project Safety Packet.
    1. Hazardous materials, at a minimum, refer to asbestos, lead, mercury, polychlorinated biphenyl (PCB), and containerized chemicals.
    2. On every project involving existing facilities, a hazardous materials survey shall be performed prior to any demolition. This survey will be performed by OSU Environmental Health and Safety (EH&S) or by independent consultants as directed by EH&S.
    3. The survey will provide an overview of typical surfaces and locations containing the hazardous material in question but may not specifically delineate every location where the hazardous material may be found. Under no circumstance shall demolition work occur prior to approval from OSU EH&S.
    4. All contractors are responsible to contacting OSU EH&S prior to any construction activities or demolition of existing structures within an OSU building.
    5. If the Contractor observes or suspects the existence of hazardous materials in the structure or components of the building, the Contractor shall immediately stop work and notify the OSU Project Manager. 
    6. Schedule ten (10) days of slack or "down" time for the removal of hazardous materials without penalty to OSU for the delay of the Contract.
    7. Contractor shall follow OSHA guidelines involving exposure to workers in addition to the requirements of DEQ and EPA.
    8. Removal of asbestos shall be performed by an OUS-approved asbestos contractor under the direction of OSU EH&S. Refer to Section 02 82 00 – Asbestos Remediation.
    9. Lead abatement projects shall be performed by OUS-approved lead abatement contractor under the direction of OSU EH&S. Lead abatement projects have the intent to remove (or encapsulate) lead surfaces to make them less hazardous.  See Section 02 83 00: Lead Remediation.
    10. Demolition of surfaces with lead-containing paint is NOT considered lead abatement. If contractors, for any reason, cannot perform demolition on lead-containing materials, a separate contractor will be hired by OSU for that work.
    1. Discharge of pollutants (any substance, material, or waste other than clear, uncontaminated storm water) into a storm drain system or a water body is prohibited by the Department of Environmental Quality (DEQ).
    2. Any proposed new development or expansion of development along an open natural drainage way shall comply with OSU Zoning District Section Drainageway Management Agreement. Where applicable, consider water quality and/or detention swales that use biological methods for water purification to address unavoidable post- development storm water sources.
    3. Storm water runoff from loading dock areas shall be drained to a sanitary sewer system where feasible. Where sanitary sewer is not available, best management practices must be implemented.
    4. All wastewater generated from water wash down and other cleaning activities within confined animal facilities and that contacts manure areas must be handled so as to not impair ground or surface water quality as defined by local jurisdiction.
