### 1 Env-A 2300 CHAPTER Env-A 2300 MITIGATION OF REGIONAL HAZE

PART Env-A 2301 PURPOSE Env-A 2301.01 Purpose. This chapter establishes emission standards for c ertain fossil-fuel-fired steam generating units for the purpose of reducing emissions that contribute to regional haze. These limitations are necessary to ensure compliance with section 169A of the Act (42 U.S.C. 7491) and regio nal haze program requirements established at 40 CFR 51. 308, including, but not limited to, provisions for Best Available Retrofit Technology (BART) [40 CFR 51.308 (e)].

PART Env-A 2302 APPLICABILITY Env-A 2302.01 Applicability. This chapter shall apply to any fossil-fuel-fired steam generating unit of the following types whose maximum heat inpu t rate is more than 1,000 million BTUs per hour: (a) Cyclone-firing, wet-bottom boilers fueled by c oal or any combination of fuels using coal; and (b) Tangential-firing, dry-bottom boilers fueled b y oil, gas, liquid biofuel, or any combination of oil, gas, and liquid biofuel.

PART Env-A 2303 DEFINITIONS Env-A 2303.01 “Best Available Retrofit Technology (BART)” means an emission limitation based on the degree of reduction achievable through the a pplication of the best system of continuous emissio n reduction for each pollutant which is emitted by an existing stationary facility, as defined in 40 CFR 51.301. The emission limitation must be establishe d, on a case-by-case basis, taking into considerati on the technology available, the costs of compliance, the energy and nonair quality environmental impacts of compliance, any pollution control equipment in use or in existence at the source, the remaining useful life of the source, and the degree of improvement in vis ibility which may reasonably be anticipated to resu lt from the use of such technology.

Env-A 2303.02 "Coal" means coal as defined in Env-A 1211.02. Env-A 2303.03 "Gas" means gas or gaseous fuel as de fined in Env-A 1211.02. Env-A 2303.04 “Liquid biofuel” means any liquid fue l such as biodiesel or cellulosic ethanol that is derived from renewable biological raw materials such as plants or food waste. Env-A 2303.05 "Maximum heat input rate" means maxim um heat input rate as defined in Env-A 1211.02. Env-A 2303.06 “Oil” means any petroleum-based liqu id fuel oil, including distillate and residual fuel oils. Env-A 2303.07 “Regional haze” means any humanly per ceptible degradation in visibility from that which would have existed under natural conditions, caused by the presence of fine-particle air polluta nts and their precursors originating from many sources over a wide geographic area. Env-A 2303.08 “Stack test” means the sampling, anal ysis, and reporting of emissions from a stationary point source in accordance with testing procedures specified in Env-A 802.Draft NEW HAMPSHIRE CODE OF ADMINISTRATIVE RULES 01 /26/10



### 2 Env-A 2300 Env-A 2303.09 “Total suspended particulate matter ( TSP)” means particulate matter as measured by the high-volume method described in Appendix B o f 40 CFR Part 50.

PART Env-A 2304 PERFORMANCE TESTING Env-A 2304.01 Performance Testing Requirements App licable to Tangential-Firing, Dry-Bottom Boilers. For any tangential-firing, dry-bottom boiler subj ect to this chapter, performance tests shall be conducted as follows: (a) Performance testing for sulfur dioxide (SO 2 ) emissions, nitrogen oxide (NOx) emissions, and total suspended particulate matter (TSP) emissions shall meet the requirements established by valid permit in accordance with Env-A 600; and (b) Any stack test required under this part shall be co nducted in accordance with the requirements of Env-A 802. Env-A 2304.02 Performance Testing Requirements App licable to Cyclone-Firing, Wet-Bottom Boilers. For any cyclone-firing, wet-bottom boiler subject to this chapter, performance tests shall be conducted as follows: (a) Performance testing for sulfur dioxide (SO 2 ) emissions and nitrogen oxide (NOx) emissions shall meet the requirements established by valid pe rmit in accordance with Env-A 600; (b) Periodic stack tests for total suspended particulat e matter (TSP) emissions shall be conducted in accordance with the following protocol:

(1) For an initial period of three years, stack tests s hall be conducted annually, with the first stack test to be completed by June 30, 2013; (2) Beginning on July 1, 2015, stack tests shall be con ducted every other year, with the fourth stack test to be completed by June 30, 2017. (3) At facilities where an affected unit shares a commo n stack with a second affected unit, the stack emissions shall be tested as from one source, by either of the following methods:

a. With both units operating simultaneously, a stack t est on the combined emissions from both units, or b. With one unit operating at a time, separate stack t ests on the emissions from each unit; and (c) All stack tests shall be conducted in accordance wi th the requirements of Env-A 802.

PART Env-A 2305 EMISSION STANDARDS FOR MITIGATION OF REGIONAL HAZE Env-A 2305.01 Emission Standards Applicable to Tan gential-Firing, Dry-Bottom Boilers. For any tangential-firing, dry-bottom boiler subject to thi s chapter, the following emission rates shall apply : (a) Beginning on July 1, 2013, sulfur dioxide (SO 2 ) emissions shall not exceed 0.50 lb per million BTUs on a calendar monthly average basis as recorde d by a continuous emissions monitoring system (CEMS) in accordance with Env-A 2306;Draft NEW HAMPSHIRE CODE OF ADMINISTRATIVE RULES 01 /26/10



### 3 Env-A 2300 (b) Nitrogen oxide (NOx) emissions shall not exceed lim itations established by valid permit in accordance with Env-A 600; and (c) Total suspended particulate matter (TSP) emissions shall not exceed limitations established by valid permit in accordance with Env-A 600.
