Deanna Walsh - 4 - 8 October 2002 <br /> Mossdale Landing Draft EIR <br /> submit an NOI to comply with the permit to the State Water Resources Control Board and an SWPPP <br /> must be prepared. <br /> Water Ouality Certification - Wetlands <br /> If a U.S. Army Corp of Engineers (ACOE)permit is required due to the disturbance of wetlands,then <br /> Water Quality Certification must be obtained from the Regional Board prior to initiation of project <br /> activities. Section 401 of the federal Clean Water Act requires that the project proponent for any project <br /> that impacts surface waters of the United States (such as streams and wetlands) must request a 401 <br /> Water Quality Certification from the Regional Board. Water Quality Certification must be obtained prior <br /> to initiation of project activities. The proponent must follow the ACOE 404(b)(1) Guidance to assure <br /> approval of their 401 Water Quality Certification application. The guidelines are as follows: <br /> 1. Avoidance (Is the project the least environmentally damaging practicable alternative?) <br /> 2. Minimization(Does the project minimize any adverse effects to the impacted wetlands?) <br /> 3. Mitigation (Does the project mitigate to assure a no net loss of functional values?) <br /> Dewatering Permit <br /> The proponent may be required to file a Dewatering Pen-nit covered under Waste Discharge <br /> Requirements General Order for Dewatering and Other Low Threat Discharges to Surface Waters <br /> Permit, Order No. 5-00-175 (NPDES CAG995001). The following discharges may be covered by this <br /> permit provided they do not contain significant quantities of pollutants and are either(1) four months or <br /> less in duration, or(2) the average dry weather discharge does not exceed 0.25 mgd: <br /> a. Well development water <br /> b. Construction dewatering <br /> c. Pump/well testing <br /> d. Pipeline/tank pressure testing <br /> e. Pipeline/tank flushing or dewatering <br /> f. Condensate discharges <br /> g. Water Supply system discharges <br /> h. Miscellaneous dewatering/low threat discharges <br /> Industrial Stormwater Permit <br /> Depending on the Standard Industrial Classification(SIC) code of the final project, compliance with the <br /> NPDES General Permit No. CAS000001 for Discharges of Storm Water Associated With Industrial <br /> Activities may be required. The SIC codes of activities requiring coverage are listed in the General <br /> Permit. In order to obtain coverage by the General Permit, the proponent must submit a Notice of Intent <br /> to comply with the permit (NOI)to the State Water Resources Control Board and a Storm Water <br /> Pollution Prevention Plan (S WPPP) must be prepared. <br /> Section 404 Permit <br /> If the project will involve the discharge of dredged or fill material into navigable waters or wetlands, a <br /> permit pursuant to Section 404 of the Clean Water Act may be needed from the US Army Corps of <br /> Engineers. If a Section 404 permit is required by the Corps, the Board will review the permit application <br /> to ensure that discharge will not violate water quality standards.
