(17) Groundwater/Soil Venting Systems. Construction, substantial reconstruction or alteration of any Contaminated Groundwater Treatment System (CGTS) or contaminated soil venting system complying with the following criteria: (a) CGTS or contaminated soil venting systems shall be equipped and operated such that the system continuously reduces VOC in air effluent stream by at least 95% (by weight). Such systems include, but are not limited to, the following: 1. CGTS followed by carbon adsorber, incinerator or equivalent air pollution control device; or 2. Contaminated soil venting followed by carbon adsorber, incinerator or equivalent air pollution control device. (b) Systems shall be equipped and operated with the necessary procedures and instrumentation to assure operation in compliance with this standard including, but not limited to: 1. Interlock to prevent operation of the entire system without proper control device operation including, but not limited to, automatic shutoff if incinerator drops below normal operating temperature; 2. Inlet/outlet incinerator temperature indicators; 3. For a CGTS, flowmeter(s) indicating rate and total amount of groundwater being treated, if applicable; and 4. On-site regeneration of carbon or regularly scheduled replacement of carbon, if used. (d) Sufficient records shall be prepared and maintained to demonstrate emissions compliance for each month. Records shall include, but are not limited to the following, as applicable: 1. Once per month, measurement of water flow rate and total flow to date for the month; 2. For a CGTS, once per month measurement of inlet and effluent water VOC concentration; 3. Once per month, measurement of VOC concentration in air prior to control, and VOC concentrations after control; 4. Once per month, measurement of overall VOC reduction efficiency of the air pollution control system in percent by weight; 5. Maintenance records of the system; 6. Monthly operating hours of the system; 7. Once per month, measurement of incinerator outlet temperatures; and 8. Carbon regeneration/replacement records. (18) Fuel Cells. Construction, substantial reconstruction or alteration of any fuel cell(s) complying with the following criteria: (a) The emissions from the fuel cell will not exceed the following standards based upon a one hour averaging time: 1. NOx - 0.03 pounds per megawatt hour. 2. Carbon Monoxide - 0.05 pounds per megawatt hour. 3. Non methane organic compounds - 0.008 pounds per megawatt hour. (b) Any person subject to 310 CMR 7.03(18) shall keep records of monthly electric generation. (19) Flexographic, Gravure, Letterpress and Screen Printing. On and after May 1, 1998, construction, substantial reconstruction, or alteration of any flexographic, gravure, letterpress, or screen printing press at a facility that is not subject to 310 CMR 7.26(20) through (29), but that is utilizing materials containing VOC or organic material including, but not limited to, printing inks and overprint coating, alcohol, makeup solvents, and cleanup solutions complying with the applicable performance standards in 310 CMR 7.26(25) and 310 CMR 7.26(26), shall be subject to the limits and reporting requirements in either 310 CMR 7.03(19)(a)1. or 2. and shall also be subject to the requirements in 310 CMR 7.03(19)(c) and to the recordkeeping requirements in 310 CMR 7.03(19)(b). (a) 1. The total facility including, but not limited to, the new or modified printing press, and non-printing operations at the facility, shall use less than 670 gallons per calendar month of all materials containing VOCs or, alternatively, the total facility emission rate shall be less than 2.5 tons of VOC per calendar month. The owner/operator is subject to the reporting requirements of 310 CMR 7.12; or 2. The total facility including, but not limited to, the new or modified printing press, and non-printing operations at the facility, shall use less than 2,000 gallons per 12-month rolling period of all materials containing organic material (includes VOC) or, alternatively, the total facility emission rate shall be less than ten tons of organic material (includes VOC) per 12-month rolling period. The owner/operator is not subject to the reporting requirements of 310 CMR 7.12 unless otherwise required. (b) Any person subject to 310 CMR 7.03(19) shall maintain records sufficient to demonstrate compliance. Such records shall include, but are not limited to, records demonstrating that cleanup solutions, inks, coatings, and adhesives are in compliance with applicable standards set forth in 310 CMR 7.26(20) through (29) and that the usage rate or the emissions rate do not exceed the rates set forth in 310 CMR 7.03(19)(a). Records kept to demonstrate compliance shall be kept on site for five years and shall be made available to representatives of the Department upon request. (c) Any person who complies with 310 CMR 7.03(19), in lieu of obtaining a plan approval for a press under 310 CMR 7.02, shall comply with applicable RACT requirements of 310 CMR 7.18(12) and (25) and 310 CMR 7.26(20) through (29) when such requirements become more stringent than those in 310 CMR 7.03(19).
