Volume 2: Draft Gorst Planned Action Environmental Impact Statement

GORST PLANNED ACTION EIS | AFFECTED ENVIRONMENT, SIGNIFICANT IMPACTS, AND MITIGATION MEASURESIssues associated with movement of hazardous materials in stormwater from existing sites would be similar tothose under Alternative 2. Bremerton Auto Wrecking Landfill would continue to be a site of particular concern,with contaminated waste carried offsite during flooding events. Implementation of the WatershedCharacterization & Framework Plan and Gorst Subarea Plan would help address flooding and stormwaterinfiltration issues throughout the watershed, which would help minimize the amount of flooding onto developedareas and associated movement of hazardous materials in surface water.Mitigation MeasuresIncorporated Plan FeaturesThe Watershed Characterization & Framework Plan and Gorst Subarea Plan do not contain features that arespecific to hazardous materials. However, features of both plans would have the indirect benefit of reducing risksof exposure to hazardous materials over the long term. Regardless of the land use alternative selected, the GorstUGA would no longer have the urban industrial designation, meaning that new developments would have a lowerpotential for releases of hazardous materials than some current land uses.Features of the Watershed Characterization & Framework Plan and Gorst Subarea Plan that would minimizeflooding and increase infiltration of stormwater would help reduce risks of surface water contamination byreducing the likelihood that flood water or stormwater would run onto contaminated sites such as the BremertonAuto Wrecking Landfill. These stormwater features are discussed in detail in Section 3.2 Water Resources.Applicable Regulations and CommitmentsFederal hazardous material and waste laws and regulations would be applicable to hazardous substances used,stored, or generated by the project. Applicable federal laws include the RCRA; Hazardous and Solid WasteAmendments; CERCLA (aka Superfund); and Superfund Amendments and Reauthorization Act. Pursuant toregulations promulgated under Section 102 of CERCLA, as amended, release of a reportable quantity of ahazardous substance to the environment in a 24-hour period must be reported to the National Response Center(40 CFR Part 302). Similarly, Washington hazardous material and waste laws and regulations would be applicableto hazardous substances used, stored, and generated by the project. The Model Toxics Control Act (mobilesource air toxics) requires reporting of a release of any hazardous substance within 90 days of the release (orwithin 24 hours for releases from a UST; WAC 173-340-300). Cleanup activities at contaminated sites areconducted under the MTCA and disposal of contaminated materials are conducted under the RCRA.Demolition of older facilities may require asbestos and lead-based paint mitigation. Under the WashingtonDepartment of Safety and Health asbestos standards (WAC 296-62, 296-65, and 296-155), thermal systeminsulation (pipe lagging, boiler insulation, etc.), surfacing materials (spray-on acoustical plasters, troweled onplaster coatings, etc.) and flooring materials (vinyl tile, sheet goods, etc.) are all presumed to contain asbestos inbuildings built before 1981 unless these materials are shown not to contain asbestos by a certified contractor.Demolition of asbestos in the project area is regulated by the Puget Sound Clean Air Agency (Article 4: AsbestosControl Standards) and requires an asbestos survey, a notification of demolition, verification that all asbestos wasproperly removed, and proper disposal of the asbestos-containing materials.The Washington State Department of Commerce (Chapter 365-230 WAC) regulates certification, accreditation,enforcement and compliance for firms and individuals to use lead-safe work practices when working on pre-1978homes or child-occupied facilities. The regulations apply to training and certification requirements for individualsand firms and to accreditation requirements for training programs.Other Potential Mitigation MeasuresThe following general mitigation measures would minimize or eliminate construction impacts within the StudyArea and could be incorporated into the Planned Action Ordinance.Draft | June 2013 3-96
