PART I Page 10 of 48 Permit No.: C00038342 The permittee must enclose or cover storage piles of salt, or piles containing salt, used for deicing or other commercial or industrial purposes, including maintenance of paved surfaces, and implement appropriate measures to minimize exposure resulting from adding to or removing materials from the pile. h. 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 dischargebf 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 (Outfall 001) Note that acute WET testing is applicable to outfall 001 due to the intermittent nature of the discharge. To meet the definition of an intermittent discharge in the policy, Implementation of the Narrative Standard for Toxicity in Discharge Permits Using Whole Effluent Toxicity (Sept 30, 2010), one of the following must apply: A) The maximum discharge frequency is less than 3 consecutive days (72 hours), and less than 3 days per 7day period, and less than 10 days total per month. B) The maximum discharge frequency is less than 5 consecutive days (120 hours) and less than 5 days total per month. C) It can be shown that discharge frequency and duration is tied solely to precipitation events, where the discharge starts and stops shortly after the precipitation event starts/stops. 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.
