Ohio Administrative Code › Title 1501:10 - Division of Mineral Resources Management - Mine Safety › Chapter 1501:10-2 - Diesel Equipment in Underground Coal Mines › Section 1501:10-2-05 - Exhaust emissions control and conditioning systems

Current through all regulations passed and filed through July 1, 2024
(A) 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
			 (C) of this rule, using the ISO 8178-1 test and has resulted in diesel
			 particulate matter emissions that do not exceed an average concentration of
			 0.12 milligrams per cubic meter (mg/m3) of air when diluted by one hundred per
			 cent of the MSHA 30 C.F.R. Part 7 approval plate ventilation rate for that
			 diesel engine. The website for the ISO International Organization for
			 Standardization is
http://www.iso.org/iso/home.html
.
			 Should MSHA promulgate new regulations that change the 30 C.F.R. Part 7
			 approval plate ventilation rate, the dilution percentage relative to the
			 approval plate ventilation rate will be increased or decreased on a direct
			 ratio basis as approved by the chief.
(B) The exhaust emissions control and
			 conditioning system shall be 
								capabale of successfully
			 completing a single series of laboratory tests
			 conducted at a laboratory accepted by the chief for each diesel
			 engine.
(C) An exhaust emissions
			 control and conditioning system may be approved by the chief for multiple
			 diesel engine applications through a single series of ISO 8178-1 laboratory
			 tests, only if data is provided to the chief and he or she determines that the
			 exhaust emissions control and conditioning system will meet, for each diesel
			 engine, the in- laboratory diesel particulate matter standard established in
			 paragraph (A) of this rule. Data provided to the chief
			 
								is to
			 include diesel particulate matter production rates for each engine as measured
			 during an ISO 8178-1 test, if available. If ISO 8178-1 test data for diesel
			 particulate matter production is not available for a specific diesel engine,
			 comparable data may be provided to the chief that reliably verifies that the
			 exhaust emissions control and conditioning system will meet, for that diesel
			 engine, the in-laboratory diesel particulate matter standard established in
			 paragraph (A) of this rule. This standard  only applies to in-laboratory testing for
			 approval of diesel-powered equipment for use underground.
(D) Components of exhaust emissions system.
			 The following provisions apply to any exhaust
			 emissions control and conditioning system :
(1) A diesel
			 particulate matter (DPM) filter that has proven to be capable of a reduction in
			 total diesel particulate matter to a level that does not exceed
			  paragraph (A) of this
			 rule. However, the chief may evaluate alternative
			 technologies that have the ability to meet the standard of paragraph (A) of
			 this rule;
(2) An oxidation
			 catalyst or other gaseous emissions control device capable of reducing
			 undiluted carbon monoxide emissions to one hundred parts per million (ppm) or
			 less under all conditions of operation at normal engine operating temperature
			 range;
(3) An engine surface
			 temperature control capable of maintaining significant external surface
			 temperatures below three hundred and two degrees Fahrenheit;
(4) A system capable of reducing the exhaust
			 gas temperature below three hundred and two degrees Fahrenheit;
(5) An automatic engine shutdown system that
			 shuts off the engine before the exhaust gas temperature reaches three hundred
			 and two degrees Fahrenheit and, if water-jacketed components are used, before
			 the engine coolant temperature reaches two hundred and twelve degrees
			 Fahrenheit. A warning 
									is to be provided to alert the equipment operator
			 prior to engine shutdown;
(6) A
			 spark arrestor system;
(7) A flame
			 arrestor system;
(8) A sampling
			 port for measurement of undiluted and untreated exhaust gases as they leave the
			 engine;
(9) A sampling port for
			 measurement of treated undiluted exhaust gases before they enter the mine
			 atmosphere; and
(10) For
			 permissible diesel equipment, compliance with any
			 additional MSHA regulations .
