Employee Training The permittee must develop and implement a training program for employees. Training must be conducted at Least annually, and must address the following, as applicable to the trainee's activities: the site-specific control measures used to achieve the permit effluent limits, components and goals of the SWMP, monitoring and inspection procedures, and other applicable requirements of the permit. At a minimum, the following individuals must be trained: i. Employee(s) overseeing implementation of, revising, and amending the SWMP. ii. Employee(s) performing installation, inspection, maintenance, and repair of control measures. iii. Employee(s) who work in areas of industrial activity subject to this permit. iv. Employee(s) who conduct stormwater discharge monitoring required by this permit. i. Waste, Garbage and Floatable Debris The permittee must minimize the discharge of waste, garbage, and floatable debris from the site by keeping exposed areas free of such materials or by intercepting them before they are discharged. j. Dust Generation and Vehicle Tracking of Industrial Materials. The permittee must minimize generation of dust and off-site tracking of raw, final, or waste materials. D. SPECIFIC MONITORING REQUIREMENTS 1. Acute Wet Testing (Outfalls 007 and 008) a. General Acute WET Testing and Reporting Requirements The permittee shall conduct an acute 48-hour WET test using Ceriodaphnia dubia, and an acute 96 -hour WET test using Pimephales promelas. Acute tests shall be conducted as a static replacement test using a single effluent grab sample. The permittee shall conduct each acute WET test in accordance with the 40 CFR Part 136 methods described in Methods for Measuring the Acute Toxicity of Effluents and Receiving Water to Freshwater and Marine Organisms, Fifth Edition, October 2002 (EPA -821-R-02-012) or its most current edition. The following minimum dilution series should be used: 0% effluent (control), 20%, 40%, 60%, 80%, and 100% effluent. If the permittee uses more dilutions than prescribed, and accelerated testing is to be performed, the same dilution series shall be used in the accelerated testing as was used in the failed test. Tests shall be done at the frequency listed in the EFFLUENT LIMITATIONS AND MONITORING REQUIRMENTS section. Test results shall be reported along with the Discharge Monitoring Report (DMR) submitted for the end of the reporting period when the sample was taken. (i.e., WET testing results for the calendar quarter ending March 31 shall be reported with the DMR due April 28, etc.) The permittee shall submit all laboratory statistical summary sheets, summaries of the determination of a valid, invalid or inconclusive test, and copies of the chain of custody forms, along with the DMR for the reporting period. If a test is considered invalid, the permittee is required to perform additional testing during the monitoring period to obtain a valid test result. Failure to obtain a valid test result during the monitoring period shall result in a violation of the permit for failure to monitor.
