Ohio Admin. Code 1501:10-2-20 - Establishing baseline exhaust emissions values for monitoring and control
(A) Exhaust
emissions for diesel-powered equipment shall be monitored and controlled using
the control and conditioning systems of rule 1501:10-2-05 of the Administrative Code, the threshold limits and other requirements of rule 1501:10-2-07 of the Administrative Code, the baseline exhaust emissions values established in this rule, and the diagnostic testing of rule 1501:10-2-21 of the Administrative Code.
(B)
Establishing baseline exhaust emissions values. For purposes of diagnostic
testing under rule 1501:10-2-21 of the Administrative Code, baseline exhaust emissions values shall be established in accordance with this rule for each piece of diesel-powered equipment to be used in a specific underground coal mine.
(1) The
chief shall approve baseline carbon monoxide (CO) values that are
representative of the MSHA lug curve for that specific engine model. If the
baseline CO values are greater than the MSHA lug curve values, the chief shall
investigate and approve, disapprove, or provide an alternate operating
procedure for meeting the requirements of this rule under the condition that CO
baseline exhaust emissions remain representative of MSHA's approval
data.
(2) The chief shall establish
the loaded condition for the baseline exhaust emissions testing under
paragraphs (C)(12) to (C)(13) of this rule by determining carbon dioxide (CO2)
values that are representative of the MSHA lug curve readings for that engine
model and horsepower.
(3) When any
diesel-powered machine first enters service at a mine, a mechanic qualified in
accordance with rule 1501:10-2-24 of the Administrative Code shall establish the baseline exhaust emissions values, other than the CO and CO2 emissions values approved or established by the chief under paragraphs (B)(1) and (B)(2) of this rule, by following the procedure of paragraph (C) of this rule or an approved alternative procedure of paragraph (D) of this rule.
(C)
When establishing baseline exhaust emissions values, equipment may be located
either on the surface or underground. Unless the chief approves an alternative
procedure for establishing baseline exhaust emissions values pursuant to
paragraph (D) of this rule, a mechanic qualified in accordance with rule 1501:10-2-24 of the Administrative Code shall establish baseline exhaust emissions values in accordance with the following:
(1) Verify
that the seal on the engine fuel injector pump is in place and that the proper
fuel pump is on the equipment;
(2)
Install a new, clean intake air cleaner, then measure and record the intake
restriction pressure, and ensure the pressure meets the manufacturer's
specifications;
(3) Check the level
of engine oil and add oil, if necessary;
(4) Change the engine lubrication oil (if not
fresh);
(5) Check the level of the
transmission fluid and add fluid if necessary;
(6) Measure and record the exhaust gas
backpressure and, if exhaust gas backpressure is above that specified by the
manufacturer, take steps to bring the exhaust gas backpressure back within the
manufacturer's recommended limit prior to again beginning the procedure to
establish the baseline exhaust emissions values pursuant to paragraph (C) of
this rule;
(7) Test the brakes and
ensure the brakes are in good working order a
as specified by the
manufacturer;
(8) If the baseline
exhaust emissions values are being established on equipment that is
underground, place the equipment into an intake entry;
(9) Set the brakes and chock the
wheels;
(10) Install an exhaust gas
analyzer in proper working condition into the untreated exhaust gas
port;
(11) Start the engine and
allow it to warm up to operating temperature;
(12) Put the engine into a loaded
condition;
(13) Start the exhaust
gas analyzer and allow the engine to operate in the loaded condition for a
sufficient length of time, but not less than a ninety-second duration to insure
proper CO readings. The qualified mechanic shall record both CO and CO2
readings; and
(14) Comply with
record keeping requirements of rule 1501:10-2-17 of the Administrative Code.
(D)
The chief may approve an alternative to the procedure to establish the baseline
exhaust emissions values of paragraph (C) of this rule.
(E) The results of the procedures to
establish the baseline exhaust emissions values under this rule shall be
submitted to and approved by the chief prior to being implemented for each
engine and equipment type.
