Title 310 CMR 7.00 - Air Pollution Control
Section 7.12 - U Source Registration

1. Has a facility-wide maximum energy input capacity in BTU/hour from fuel utilization facilities equal to or greater than the following size thresholds:

2. Has a maximum energy input capacity in Btu/hour from any fuel utilization facility emission unit that combusts natural gas, propane, butane, or distillate oil equal to or greater than the 10,000,000 Btu/hour.

3. Has non-combustion federal potential1 to emit (facility-wide) equal to or greater than:

1 Non-combustion potential emissions excludes emissions from motor vehicles, incinerators and products of combustion from fuel utilization facilities.

4. Is or contains a hazardous waste incinerator, regardless of size.

5. Is or contains an incinerator with the capacity to reduce 50 pounds per hour or more of waste.

6. Is or contains an emission unit or process that is subject to a National Emission Standard for Hazardous Air Pollutants (NESHAP) or subject to a Maximum Achievable Control Technology (MACT) standard defined at 40 CFR Part 61 and Part 63 , for which the Department has received delegation from EPA.

7. Is or contains a stationary reciprocating internal combustion engine (except for emergency or standby engines) with a maximum energy input capacity of 3,000,000 Btu per hour or greater (burning any fuel).

8. Is required to submit a Source Registration as a condition of a plan approval or operates under a Restricted Emission Status (RES) pursuant to 310 CMR 7.02(9) or 7.02(10) issued since January 1, 1990. The owner/operator of a facility required by a plan approval, issued prior to January 1, 1990, to submit an annual Source Registration is no longer required to do so unless such facility meets one of the other applicability criteria in 310 CMR 7.12 or a more recent Department approval requires submittal of a Source Registration.

9. Is a facility for which the owner/operator has received a request from the Department to submit a Source Registration.

10. Is a facility subject to 310 CMR 7.00: Appendix C in the previous calendar year.

11. Had actual emissions equal to or greater than 0.5 tons of lead, 25 tons of NO, or 25 tons of VOC in the previous calendar year.

1. May 1st for a facility subject to 310 CMR 7.00: Appendix C in the previous calendar year;

2. June 1st for a facility that:

1. A complete description of the facility, including a description of process and combustion equipment, facility operating hours and operating schedule, and raw materials and fuels used at the facility. Once a facility is subject to 310 CMR 7.12, all emission units and processes at the facility shall be included in the Source Registration even if, individually, certain emission units and processes may not meet the applicability thresholds of 310 CMR 7.00. Emission units that are "insignificant activities" under 310 CMR 7.00: Appendix C(5)(i) need not be included;

2. Detailed emissions estimates for all criteria and hazardous air pollutants emitted at the facility;

3. An Emission Statement summarizing and certifying actual annual emissions and peak ozone season day emissions of volatile organic compounds and oxides of nitrogen;

4. A description of air pollution control equipment and capture and control efficiencies of said equipment;

5. Calculations and assumptions used to support calculations of emissions such as annual fuel process rate, and peak ozone season daily process rate; and

6. Certification of accuracy to ensure that the information contained in the Source Registration is accurate and complete to the best knowledge of the Responsible Official signing the submittal pursuant to 310 CMR 7.01.
