WASTE DISCHARGE REQUIREMENTS -5- CALIFORNIA AMMONIA COMPANY CALAMCO - STOCKTON TERMINAL SAN JOAQUIN COUNTY hydropower generation; and preservation and enhancement of fish, wildlife and other aquatic resources. The beneficial uses of the underlying ground water are municipal and domestic, industrial, and agricultural supply. The permitted discharge is consistent with the antidegradation provisions of 40 CFR 131.12 and State Water Resources Control Board Resolution 68-16. The impact on existing water quality will be insignificant. The action to adopt an NPDES permit is exempt from the provisions of Chapter 3 of the California Environmental Quality Act (CEQA) (Public Resources Code Section 21100, et seq.), in accordance with Section 13389 of the California Water Code. Federal regulations for storm water discharges were promulgated by the EPA on 16 November 1990 (40 CFR Parts 122, 123, and 124). The regulations require specific categories of facilities, which discharge storm water associated with industrial activity (storm water), to obtain NPDES permits and to implement Best Available Technology Economically Achievable (BAT) and Best Conventional Pollutant Control Technology (BCT) to reduce or eliminate industrial storm water pollution. The SWRCB adopted Order No. 91-13-DWQ (General Permit No. CAS000001) specifying waste discharge requirements for discharges of storm water associated with industrial activities, excluding construction activities, and requiring submittal of a Notice of Intent by industries to be covered under the permit. This Order further specified that if an individual permit is adopted for storm water runoff from a facility, then the General Permit would no longer apply. This individual permit and the provisions it contains concerning stormwater relieves the Discharger from continuing coverage under the General Permit. The Discharger previously submitted a Notice of Intent for coverage by the General Permit under Major Group 42, "Motor Freight Transportation and Warehousing." The Board has notified the Discharger and interested agencies and persons of its intent to prescribe waste discharge requirements for this discharge and has provided them with an opportunity for a public hearing and an opportunity to submit their written views and recommendations.
