§22A-2A-403 Exhaust emissions control and conditioning systems. - West Virginia Statutes

§22A-2A-403. Exhaust emissions control and conditioning systems.
(a) All exhaust emissions control and conditioning systems and their component devices shall be approved by the West Virginia diesel equipment commission. Such approval requires compliance with applicable standards and procedures established by rules of the commission for the use of the system or device in reducing or eliminating diesel particulate matter, carbon monoxide and oxides of nitrogen.

The rules of the commission shall require all exhaust emissions control and conditioning systems to undergo an initial series of laboratory tests, using test equipment requirements and standard procedures approved by the commission for testing for gaseous and particulate emissions. The commission shall compile a list of acceptable third-party laboratories where testing is performed competently and reliable results are produced.

(b) Requirements and standards for exhaust emissions control and conditioning systems include, but are not limited to, the following:

(1) A minimum standard, stated as an average percentage, for the reduction of diesel particulate matter emissions by a diesel particulate matter filter or other comparably effective emissions control device;

(2) A minimum standard, stated in parts per million, for the reduction of emissions of undiluted carbon monoxide, using an oxidation catalyst or other gaseous emissions control device;

(3) A minimum standard, stated in parts per million, for the reduction of emissions of oxides of nitrogen, using advanced control technology such as catalytic control technology or other comparably effective control methods;

(4) Any additional requirements established by the rules of the commission or MSHA regulations relating to requirements for permissible mobile diesel-powered transportation equipment set forth in part 36, title thirty of the code of federal regulations, 30 C.F.R. §36.1, et seq.
