Page 13 of 18 Permit No. 1177 METROPOLITAN COUNCIL ENVIRONMENTAL SERVICES Attachment B Baseline Monitoring Report Requirements The following information shall be submitted as part of the Baseline Monitoring Report (BMR): 1. Identifying information - The name and address of the facility, including the name of the operator(s) and owner(s). 2. Permits - A list of any environmental control permits held by or for the facility. Description of operations - A brief description of the nature, average rate of production rate and SIC code(s) for each of the operation(s) conducted by the Permittee. This description should include a schematic process diagram which indicates points of discharge to public sewers from the regulated processes. 4. Flow measurement - The average daily and maximum daily flow, in gallons, to public sewers from each of the regulated process streams. 5. Measurement of pollutants - The results of sampling and analysis identifying the nature and concentration (or mass where necessary) of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations. The Pemnittee shall take a minimum of three representative samples, one composite for each operating day. (Samples shall be taken as outlined in Section B of this Permit.) The BMR shall indicate the time, date and place of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to public sewers. 6. Certification - A statement, reviewed by an authorized representative of the Permittee indicating whether Pretreatment Standards are being met on a consistent basis, and, if not, whether additional operation and maintenance and/or additional pretreatment equipment is required. 7. Compliance schedule, if necessary - A proposed schedule by which the Permittee will provide, in the shortest feasible time, additional operation and maintenance and/or pretreatment equipment to achieve compliance. The completion date in this schedule shall be no later than the compliance date established for the applicable EPA Pretreatment Standard. Page 14 of 18 Permit No. 1177 METROPOLITAN COUNCIL ENVIRONMENTAL SERVICES Attachment C Necessary elements of the spill control plan are: 1. A list of the name(s), titles, and phone numbers (office and home) of the persons assigned to coordinate spill response actions. 2. A eg neral description (including volumes) of stored chemicals and process tanks. Also, describe areas where chemicals are transferred or pumped. A description of controls and procedures to prevent the entry of chemicals, other materials or wastes into the sewer. Examples of such controls are: dikes, permanently sealed floor drains, specialized valves, and procedures and record keeping related to routine facility inspections. Also, note other procedures or equipment (if any) used for emergency response. 4. A description of procedures for immediate MCES notification, in the event of a spill. For example, post the Minnesota State Duty Officer at (651) 649-5451 spill phone numbers in numerous locations. Also, a description of employee training regarding MCES notification, in- house notification, and other emergency response action. 5. As part of the revised EPA General Pretreatment Regulations requirements, the spill plan should also include a list of periodic batch discharges that may constitute a "slug" discharge to the MCES treatment plant or cause your facility discharge or the MCES treatment plant discharge to violate standards. Therefore, if you conduct batch discharges of wastes, you must include them as part of your spill plan. All "significant" quantities of chemicals must be included in the spill plan. What is considered a significant quantity will vary, case by case; however, if you are storing chemicals such as solvents, oils, acids, dyes, or concentrated metal bearing solutions in containers equal to, or greater than 5 gallons, then you must include these in your plan. This volume also applies to facility areas where these types of materials or wastes are pumped or transferred in or out of containers. If you store a raw material or product such as com syrup, milk, etc., in tanks of 500 gallons or more, you must include this in your spill plan. Large volumes of materials which seem harmless have the potential to overwhelm the biological treatment process of a wastewater treatment plant and must be included in any spill plan. A pre-existing spill plan may be used to fulfill this requirement, if it is current and if it addresses the five elements above. Please note that, in the event of a spill or uncontrolled discharge, you may be held liable for damages to the collection system, and the wastewater treatment plant, and for enforcement action taken against the MCES by the Minnesota Pollution Control Agency or the U.S. EPA. Page 15 of 18 Permit No. 1177 METROPOLITAN COUNCIL ENVIRONMENTAL SERVICES Attachment D Total Toxic Organics Management Plan Requirements For EPA Metal Finishing and Electroplating Categorical Permittees Total Toxic Organics (TTO) limitations have been promulgated for all process wastewater classified as Metal Finishing and Electroplating Categorical Discharges (40 CFR 433 and 40 CFR 413). The TTO limitation is defined as the summation of all toxic organics, present in concentrations greater than 0.01 mg/1, for the toxic organic compounds identified in the attached list. Maximum daily TTO concentration limitations and compliance dates for metal finishers and electroplaters are as follows: Category TTO Limitation (m /l) Final Compliance Date Metal Finishing Electroplating-less than 10,000 gpd 2.13 4.57 Electroplating-10,000 2.13 gpd or greater February 15, 1986 July 15, 1986 July 15, 1986 The Permittee has the option of demonstrating compliance by routine TTO monitoring or by certifying that concentrated TTO organics are not discharged into public sewers. In lieu of TTO monitoring, the Permittee may select the certification alternative by submitting a certification statement in accordance with 40 CFR 433.12(a). THIS STATEMENT MUST BE INCLUDED AS AN ATTACHMENT TO ROUTINE SELF MONITORING REPORTS REQUIRED UNDER THE MCES INDUSTRIAL DISCHARGE PERMIT. The Permittee is reminded that the certification statement does not remove liability for noncompliance with the TTO limitations. The certification option WILL NOT be accepted by the Industrial Waste Section if existing monitoring data indicates noncompliance with TTO limitations or if MCES has evidence of concentrated TTO discharges into public sewers. In such cases, routine TTO monitoring will be required. Page 16 of 18 Permit No. 1177 METROPOLITAN COUNCIL ENVIRONMENTAL SERVICES Attachment D (continued) Approval of the certification alternative by the Industrial Waste Section requires the Permittee to develop and submit a TTO Management Plan that identifies the toxic organic compounds used. The TTO Management Plan shall include the following: List TTO compounds that are used in the metal finishing and electroplating processes. The list shall include the quantity/concentration of TTO compounds present in products or raw materials used in the regulated processes. Information may be based on manufacturer or supplier information. Raw materials and products may include but are not limited to: chemical additives; water treatment chemicals; cleaning compounds; and solvent degreasing agents. 2. List and diagram regulated processes where the TTO compounds identified above are used and may enter the process discharge. If the potential exists for a TTO compound to enter the process wastewater discharge, a pollutant control evaluation shall describe the in-plant control procedures used to limit or eliminate the TTO discharge. This may include chemical substitution, operational changes, spill control, recovery, reuse, or other control methods. 3. List the methods of disposal used in lieu of dumping, such as reclamation, contract hauling, or incineration. List solvent degreaser discharge volumes and frequency of discharge. Include associated TTO compounds and concentrations if present. Copies of completed hazardous waste license applications may be submitted to supplement the information requested in 14 above. However, the essential information requested must be included in the submittal.
