Ohio Admin. Code 1501:10-2-05 - Exhaust emissions control and conditioning systems
(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.htm
. 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 required to successfully
complete 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
shall 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 shall only be used for
in-laboratory testing for approval of diesel-powered equipment for use
underground.
(D)
Components of exhaust emissions system. The exhaust
emissions control and conditioning system shall include the following:
(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 the
requirements of paragraph (A) of this rule. However, the chief may request the
technical advisory committee to evaluate, in accordance with rule 1501:10-2-27 of the Administrative Code, 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 shall 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, any additional MSHA regulations must be met.
(E)
Diagnostics systems. On-board engine performance and maintenance diagnostics
systems shall be capable of continuously monitoring and giving readouts to
assure compliance with paragraphs (D)(1) to (D)(10) of this rule. The
diagnostics system shall identify levels that exceed the engine and/or
component manufacturer's recommendation or the applicable MSHA or chief's
requirements as to the following:
(1)
Engine speed;
(2)
Operating hour
meter;
(3)
Total intake restriction;
(4)
Total exhaust
gas backpressure;
(5)
Cooled exhaust gas temperature;
(6)
Cooled
temperature;
(7)
Engine oil pressure; and
(8)
Engine oil
temperature.
(F)
