Storm Water Management Plan KRC Aggregate, Inc. Lodi, California 1.0 INTRODUCTION On behalf of KRC Aggregate, Inc. (KRC), BSK&Associates (BSK) has prepared this Storm Water Management Plan (Plan) which will govern site operations with respect to eliminating storm water discharges. KRC is engaged in the mining and processing of aggregates for use in construction, with related business and maintenance activities. Operations at the site include mining, crushing, washing and sorting of sand and gravel. In 1972,the Federal Water Pollution Control Act was amended to provide that the discharge of pollutants to waters of the United States from any point source is effectively prohibited, unless the discharge is in compliance with a National Pollutant Discharge Elimination System (NPDES) permit. Amendments to the Act, made in 1987, establish a framework for regulating industrial storm water discharges under the NPDES program. Regulations, established in 1990 by the U.S.Environmental Protection Agency, require specific categories of facilities which discharge storm water associated with an industrial activity to obtain an NPDES permit. Dischargers requiring a permit are listed by category in Title 40 of the Code of Federal Regulations (CFR) Section 122.26(b)(14). Included in these categories are mining facilities. As provided for in the Final Rule, NPDES Permit Application Regulations (Federal Register/Vol. 55, No. 222, page 48032) "If the owner or operator determines that no storm water runoff comes into contact with overburden, raw material, intermediate product, finished product, byproduct, or waste products, then there is no obligation to file a permit application." 1.1 Policy and Objectives It is the policy of KRC that operations at the site be conducted in a manner appropriate for the protection, health and safety of the environment and the public at large. The purpose of the Plan is to outline operational protocols to eliminate the discharge of storm water from the facility to waters of the United States and to provide documentation demonstrating that KRC is not obligated to file a permit application or comply with monitoring and reporting requirements for storm water discharges associated with industrial activities. This document will be made available to the public at large at the offices of KRC Aggregate, Inc. from Monday through Friday between the hours of 8:00 am and 5:00 pm. KRC will maintain, on the premises, a current copy of this plan with documentation of compliance with the plan for each of the previous five years.
