[Code of Federal Regulations] [Title 40, Volume 13] [Revised as of July 1, 2005] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR63.6590] [Page 16] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 63_NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES--Table of Contents Subpart ZZZZ_National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines Sec. 63.6590 What parts of my plant does this subpart cover? This subpart applies to each affected source. (a) Affected source. An affected source is any existing, new, or reconstructed stationary RICE with a site-rating of more than 500 brake horsepower located at a major source of HAP emissions, excluding stationary RICE being tested at a stationary RICE test cell/stand. (1) Existing stationary RICE. A stationary RICE is existing if you commenced construction or reconstruction of the stationary RICE before December 19, 2002. A change in ownership of an existing stationary RICE does not make that stationary RICE a new or reconstructed stationary RICE. (2) New stationary RICE. A stationary RICE is new if you commenced construction of the stationary RICE on or after December 19, 2002. (3) Reconstructed stationary RICE. A stationary RICE is reconstructed if you meet the definition of reconstruction in Sec. 63.2 and reconstruction is commenced on or after December 19, 2002. (b) Stationary RICE subject to limited requirements. (1) An affected source which meets either of the criteria in paragraph (b)(1)(i) through (ii) of this section does not have to meet the requirements of this subpart and of subpart A of this part except for the initial notification requirements of Sec. 63.6645(d). (i) The stationary RICE is a new or reconstructed emergency stationary RICE; or (ii) The stationary RICE is a new or reconstructed limited use stationary RICE. (2) A new or reconstructed stationary RICE which combusts landfill or digester gas equivalent to 10 percent or more of the gross heat input on an annual basis must meet the initial notification requirements of Sec. 63.6645(d) and the requirements of Sec. Sec. 63.6625(c), 63.6650(g), and 63.6655(c). These stationary RICE do not have to meet the emission limitations and operating limitations of this subpart. (3) A stationary RICE which is an existing spark ignition 2 stroke lean burn (2SLB) stationary RICE, an existing spark ignition 4 stroke lean burn (4SLB) stationary RICE, an existing compression ignition (CI) stationary RICE, an existing emergency stationary RICE, an existing limited use stationary RICE, or an existing stationary RICE that combusts landfill gas or digester gas equivalent to 10 percent or more of the gross heat input on an annual basis, does not have to meet the requirements of this subpart and of subpart A of this part. No initial notification is necessary. [[Page 17]]
