Erosion control

EROSION CONTROL:

MINIMIZE SOIL EXPOSURE	TRIGGERS	GUIDANCE FOR PROJECT DEVELOPMENT	GUIDANCE FOR CONSTURCTION MANAGEMENT
	Heavy equipment use, soil disturbance and clearing. Areas of special concern include: steep slopes, floodplains, wetlands or stream banks Sensitive habitats and trees Wet season construction Large construction project	Design to follow natural contours Cleary delineate preserved vegetation on site map/plans Include appropriate buffer zones around sensitive habitats Extend buffers to include tree drip lines Project phasing (areas) must be clearly identified	Use existing roads, paths and paved/graveled areas for movement of equipment where possible Use construction fencing around preserved vegetation and sensitive areas Clip vegetation at ground level; no grubbing if possible Wet season shutdown and winterization to be implemented for multi year projects Develop separate plans for different phases with start and end dates identified for each phase
STABILIZE AND/OR MANAGE DISTURBED AREA	Project contains steep slopes, floodplains, wetlands or stream banks Disturbed soils with potential to cause turbid runoff; indirect or directly to surface waters ½ inch of rain in 24 hour period forecasted Snow melt – freeze/thaw causing runoff Include vegetation establishment criteria and inspection frequency for BMPs such as wetlands, bio-swales, etc.	Include appropriate buffer zones between construction and sensitive areas Phasing incorporated into site plan Include inspection frequency; agency notification guidelines Plan to include installation of sediment control BMPs before soil disturbance Include establishment criteria and schedule for all vegetative BMPs.	Use orange safety fencing around preserved vegetation and sensitive areas Seed or cover exposed soils immediately upon completion of final grade or phased work Inspect site within 2 hours of ½ inch of rain during work hours Develop and implement inspection and maintenance schedule
DIVERT CLEAN WATER AWAY FROM DISTURBED AREAS	Streams, waterways or ditches in project vicinity	Design water diversion techniques into grading plan Protect and use natural features to manage and infiltrate flows Promote LID site design Design and indicate methods of infiltration Identify up-gradient or upslope water sources and divert them around the project or install BMP to manage flows	Construct ditches, water bars or diversion into vegetated areas for infiltration Monitor changing conditions to identify up-gradient or upslope water sources and divert them around the project or install BMP to manage flows

POLLUTION CONTROL:

Store and use materials (and equipment) in a way that prevents releases	TRIGGERS	GUIDANCE FOR PROJECT DEVELOPMENT	GUIDANCE FOR CONSTURCTION MANAGEMENT
	Use and storage of any waste, equipment or construction material on site. Areas of special concern include: hazardous materials use Operations close to waters of the state or water conveyance system Concrete wash-outs Equipment wash Proximity to regulated or sensitive habitats		Produce and Implement a Pollution Control Plan in compliance with 00290.30. If required, produce and implement a Spill Prevention Control and Countermeasures (SPCC) plan for petroleum storage. Where possible, locate storage areas away from sensitive environments or waters of the state
Use recycled materials wherever feasible	When recycled materials are specified during design When a construction contractor requests to use an alternative recycled material	Consider use of recycled materials during design, when economically feasible Identify project generated materials which may be re-used or recycled on-site	Identify sources of usable recycled materials near project location Determine whether locally available recycled materials can be used on the project without impacting costs, engineering requirements or the environment. Identify project generated materials which may be re-used or recycled on-site
Manage waste to minimize environmental impacts	Whenever waste will be generated	Consider waste management options when it is apparent waste will be generated and provide options in the project specifications.	Develop waste management options prior to generating waste Protect waste storage areas to prevent release of pollutants Determine how wastes will be stored, disposed of and documented prior to generation
Identify contaminants and hazardous materials impacting the project as early as possible	When a project includes excavation, demolition or property acquisition.	Conduct hazardous materials assessments for projects early in the design process, following the “ODOT HazMat Program Procedures Guidebook” Prepare special provisions for management of the hazardous materials identified during construction	Follow special provisions regarding management of hazardous materials within the project. If unanticipated hazardous substances are discovered during construction stop work and notify the engineer immediately, according to 00290.20(f)
Respond to spills immediately and clean up completely	When any amount of a hazardous material is spilled	NA	Include a spill response plan in the project Pollution Control Plan (see 00290.30), and any other required pollution prevention plans Implement the spill response plan, in full, immediately. Response must include containment, required regulatory reporting and cleanup to original condition.
