Source control definition

Source control means a range of actions, for example, removal, treatment in place, and containment, designed to protect human health and the environment by eliminating or minimizing migration of or exposure to significant contamination.

Source control means the construction or installation and start-up of those actions necessary to prevent the continued release of hazardous substances or pollutants or contaminants (primarily from a source on top of or within the ground, or in buildings or other structures) into the environment.

Source control means actions taken to remove or treat soil or groundwater contamination, or both, actions taken to mini- mize the leaching of soil contamination to groundwater, and ac- tions taken to prevent the migration of groundwater contamina- tion. The term “source control” includes tank removal, the

Source control means practices to limit the generation of stormwater pollutants at their source.

Source control means stormwater management practices that control stormwater before pollutants have been introduced into stormwater; a structure or operation that is intended to prevent pollutants from coming into contact with stormwater through physical separation of areas or careful management of activities that are sources of pollutants. The 2012 Stormwater Management Manual for Western Washington separates source control BMPs into two types. Structural Source Control BMPs are physical, structural, or mechanical devices, or facilities that are intended to prevent pollutants from entering stormwater. Operational BMPs are non-structural practices that prevent or reduce pollutants from entering stormwater. See Volume IV-Source Control BMPs of the 2012 Stormwater Management Manual for Western Washington for details.

Source control means a BMP intended to prevent pollutants from entering surface and storm water and/or ground water including the modification of processes to eliminate the production or use of pollutants. Source control BMPs can be either structural or non-structural. Structural source control BMPs involve the construction of a physical structure on site, or other type of physical modification to a site; for example, building a covered storage area. A non-structural source control BMP involves the modification or addition of managerial or behavioral practices; for example, using less toxic alternatives to current products or sweeping vehicle parking lots.

Source control means a structural or operational measure to prevent or control the release or potential release of pollutants generated by certain site characteristics and uses.

Source control inspections of existing sites • What is the optimum frequency of inspections to maintain the functionality of stormwater treatment and control facilities and ensure the proper use of source control BMPs at businesses? o Which is more effective for specific high value BMPs: focusing on the property owners or focusing on the business owners, or a combination of the two?  Target both structural and operational BMP types, and situations where a business owner is and is not cooperative and willing. o Which required BMPs were implemented based upon follow up inspection? Which optional BMPs were installed based upon follow up inspection? o What were the primary barriers to not adopting or installing BMPs? o Address the connection between in-person visits and source control BMPs, and identify situations where technical assistance and/or follow-up inspections are needed to ensure required BMPs are implemented.  Gather data about percent compliance. Partner with LSC to do this study. • Are stormwater source control inspections more effective if combined with other types of inspections? How can coordination of inspections be improved or better organized regionally for referral of issues to the correct entity?

Source control means a structural measure required by the SWMM to prevent or control the release or potential release of pollutants generated by certain site characteristics and uses.
