BLIC HEARING In accordance with N.H . Admin. Rule Env-A 204.01(b) and 40CFR§ 51 .102, notice is hereby given that the New

Hampshire Department of Environmental Services, Air Resources Division, will hold a public hearing on proposed amendments to the NHCode ofAdministrative Rules on Thursday, October 14, 2004. The public hearing will be held in Room114, first floor ofthe offices ofthe Department of Environmental Services (DES), 29 Hazen Drive, Concord, NH . At 9:30 a.m

. on Thursday, October 14, 2004, DES will receive testimony fromthe public concerning Env-A 803.03, 803.04, 1211 .02(az), 1211 .12, and 1211 .21 : Auxiliary Boilers. Currently, auxiliary boilers with a heat input rate of at least 5,000,000 Btu per hour but less than 50,000,000 Btu per hour are required to performcompliance stack testing every three years. All other boilers of this size are allowed to performan efficiency test, make annual adjustments to the combustion process, and perform gaseous concentration measurements, in lieu of compliance stack testing. If adopted, the proposed amendments will allowowners and operators of small auxiliary boilers to performthe same testing activities required of other, similar-sized boilers . Another change is that Env-A 1211 .12(c) is being deleted, so that if an auxiliary boiler emits more than 50 tons per year of nitrogen oxides (NOx), it will be required to continue meeting the emission limit for auxiliary boilers instead of becoming subject to the limits for industrial boilers, which are more lenient for oil-fired boilers. In addition, the definition of "theoretical potential NOx emissions" is being moved fromEnv-A 101 to Env-A 1211 and is being amended, since it currently refers to a definition that has been repealed. DES is also proposing to delete Env-A 1211 .21(b), which requires the installation and operation of a continuous emission monitoring systemon all utility boilers, regardless of size. Testimony may be presented orally and/or in writing at the public hearing. DES will receive written comments on the proposed rules until 4:00 p.m . on Monday, October 25, 2004.
