Section 71.05 - Performance Standard for Photo Processors and Printers Without Equivalent POTW Permits That Discharge or Ship Industrial Wastewater to a POTWExcept as set forth in 310 CMR 71.05(6), each photo processor and each printer without an equivalent POTW permit that discharges or ships industrial wastewater to a POTW shall comply with the applicable requirements of 310 CMR 71.06 and the following:
(1)Discharge Limit. Each photo processor and each printer shall not discharge or ship industrial wastewater to a POTW unless the wastewater from photo processing contains no more than 2 mg/l (i.e., two parts per million) of silver, measured in accordance with 310 CMR 71.05(3). In addition, by one year from May 1, 1998 no printer shall discharge or ship to a POTW wastewater containing dischromate (chromic acid) resulting from film processor cleaning operations.(2)Operation and Maintenance. Each photo processor and each printer shall maintain a silver recovery unit in accordance with the manufacturer's or vendor's instructions to meet the 2 mg/l silver limit or limit set forth in the equivalent POTW permit, whichever is stricter.(3)Sampling and Analysis. Each photo processor and each printer shall sample its wastewater and shall analyze the sample for silver content. (a)Frequency. Sampling and analysis shall occur as frequently as necessary to demonstrate that the discharge complies with 310 CMR 71.05(1) and 71.06(2), and at least monthly, unless the Department approves a different frequency, or unless a different frequency is set in accordance with a process reviewed and approved by the Department.(b)Methodology. The sample shall be representative of wastewater composition during the selected day, and shall be taken after the photo finishing process (i.e., after combination with other wastestreams from photo processing) but prior to dilution with other wastewater. The sample shall be analyzed by a state-certified laboratory, a photographic equipment manufacturer, or a photochemical manufacturer provided that the lab uses methods prescribed in Standard Methods for the Examination of Water and Wastewater, issued by the American Health Association, American Waterworks Association, and the Water Pollution Federation, 1992 edition.(4)Recordkeeping and Reporting. Each photo processor shall keep the following records in 310 CMR 71.05(4)(a) through (f) and each printer shall keep the following records in 310 CMR 71.05(4)(a) through (f) on-site for at least three years. (a) sampling dates and results conducted in accordance with 310 CMR 71.05(3);(b) for silver recovery systems with cartridge units, date(s) of silver recovery cartridge installation and replacement;(c) for silver recovery systems without cartridge units, date(s) that the silver recovery unit is cleaned or serviced;(d) total amount of wastewater discharged in the past 12 months; and(e) total amount of wastewater passing through the silver recovery system in the past 12 months; and(f) MSDSs or other records demonstrating that film processor cleaners do not contain any chromium compounds.(5)Compliance with Board of Certified Operators of Wastewater Treatment Facilities Requirements. Each photo processor and each printer using a silver recovery system shall comply with 257 CMR 2.00: Certification of Operators of Wastewater Treatment Facilities, if applicable.(6)Printers with DEP Sewer Connection Permits. Each printer without an equivalent POTW permit that has a sewer connection permit issued by the Department pursuant to 314 CMR 7.00: Sewer System Extension and Connection Permit Program shall comply with either 310 CMR 71.05(1) through (4) or with the terms and conditions of that permit.Amended by Mass Register Issue 1321, eff. 9/9/2016.
