West Virginia Code of State Rules › Agency 196 - Diesel Equipment Commission › Title 196 - LEGISLATIVE RULE DIESEL EQUIPMENT COMMISSION › Series 196-01 - Rules For Operating Diesel Equipment In Underground Mines In WV › Section 196-1-5 - Exhaust Emissions Control

Current through Register Vol. XLI, No. 28, July 12, 2024
5.1. Underground
				diesel-powered equipment shall include an exhaust emissions control and
				conditioning system that has been laboratory tested with the diesel engine,
				except as provided in paragraph (3), using the ISO 8178-1 test and has resulted
				in diesel particulate matter emissions that do not exceed an average
				concentration of 0.12 mg over m to the third power when diluted by one hundred
				percent of the MSHA part 7 approval plate ventilation rate for that diesel
				engine. Should MSHA promulgate new regulations that change the MSHA Part 7
				approval plate ventilation rate, the dilution percentage relative to the
				approval plate ventilation rate will be adjusted either up or down on a direct
				ratio basis upon recommendation of the West Virginia Diesel
				Commission.
5.2. The exhaust
				emissions control and conditioning system shall be required to successfully
				complete a single series of laboratory tests conducted at a laboratory accepted
				by the WV Diesel Commission for each diesel engine, except as provided in
				subsection 5.3.
5.3. An exhaust
				emissions control and conditioning system may be approved for multiple diesel
				engine applications through a single series of laboratory tests, known as the
				ISO 8178-1 test, only if data is provided to the WV Diesel Commission that
				reliably verifies that the exhaust emissions control and conditioning system
				will meet, for each diesel engine, the in-laboratory diesel particulate matter
				standard established by this subsection. Data provided to satisfy this
				provision shall include diesel particulate matter production rates for the
				specified engine as measured during the ISO 8178-1 test, if available. If ISO
				8178-1 test data for diesel particulate matter production is not available for
				a specified engine, comparable data may be provided to the WV Diesel Commission
				that reliably verifies that the exhaust emissions control and conditioning
				system will meet, for the specified diesel engine, the in-laboratory diesel
				particulate matter standard established by this subsection. This standard shall
				only be used for in-laboratory testing for approval of diesel-powered equipment
				for use underground.
5.4. The
				exhaust emissions control and conditioning system shall include the following:
5.4.a. A diesel particulate matter (DPM)
				filter that has proven capable of at least a seventy-five percent reduction of
				diesel particulate matter,
5.4.b.
				An oxidation catalyst or other gaseous emissions control device capable of
				reducing undiluted carbon monoxide emissions to 100 ppm or less under all
				conditions of operation at normal engine operating temperature range.
5.4.c. An engine surface temperature control
				capable of maintaining significant external surface temperatures below three
				hundred two degrees Fahrenheit.
5.4.d. A system capable of reducing the
				exhaust gas temperature below three hundred two degrees Fahrenheit.
5.4.e. An automatic engine shutdown system
				that will shut off the engine before the exhaust gas temperature reaches three
				hundred two degrees Fahrenheit and, if waterjacketed components are used,
				before the engine coolant temperature reaches two hundred twelve degrees
				Fahrenheit. A warning shall be provided to alert the equipment operator prior
				to engine shutdown.
5.4.f. A spark
				arrestor system.
5.4.g. A flame
				arrestor system.
5.4.h. A sampling
				port for measurement of undiluted and untreated exhaust gases as they leave the
				engine.
5.4.i. A sampling port for
				measurement of treated undiluted exhaust gases before they enter the mine
				atmosphere.
5.4.j. For inby diesel
				equipment, any additional requirements of MSHA regulations at 30 CFR Part 36
				(relating to mobile diesel-powered transportation equipment for gassy noncoal
				mines and tunnels).
