Current through Register Vol. 51, No. 24, December 2, 2024
Section 26.11.29.02 - Applicability and General RequirementsA. Applicability. This chapter applies to stationary internal combustion engines used to compress natural gas located at natural gas pipeline compression stations.B. NOx Emission Limits. A person who owns or operates a stationary internal combustion engine to which this chapter applies shall perform either parametric optimization or engine rebuild to meet the following NOx emission limits: (1) Facilities with five or fewer internal combustion engines shall meet a combined maximum hourly emission limit of 300 pounds per hour or less.(2) Facilities with more than five engines shall meet a combined maximum hourly emission limit of 566 pounds per hour or less.C. NOx Emission Rates. (1) The NOx emission rates in §C(2) of this regulation apply to a stationary internal combustion engine used to compress natural gas at a natural gas pipeline compression station if the engine is one of the types and corresponding sizes identified in §C(2) of this regulation.(2) Emission Rates. Type Engine | Size (Brake HP) | NOx Emission Rate (15 Percent Oxygen) |
Spark ignited rich burn | 2400 HP or greater | 110 ppmv |
Spark ignited lean burn | 2400 HP or greater | 125 ppmv |
Diesel engines | 3100 HP or greater | 175 ppmv |
Dual fuel engines | 4400 HP or greater | 125 ppmv |
(3) The NOx emission rates in §C(2) of this regulation shall apply on and after May 1, 2003.Md. Code Regs. 26.11.29.02
