W. Va. Code R. § 45-2A-6

Current through Register Vol. XLI, No. 50, December 13, 2024

Section 45-2A-6 - /STRONG. Visible Emission Monitoring Plan Requirements

6.1. The owner or operator of a fuel burning unit(s)shall submit to the Director for approval a monitoring plan that describes the method the owner or operator will use to monitor compliance with the visible emission standard set forth in section 3 of 45CSR2. The owner or operator of a fuel burning unit may use a COMS, which shall be deemed to satisfy all of the requirements of an approved monitoring plan, or a monitoring plan as specified in subsection 6.3. in accordance with the provisions of this section.

6.1.a. Monitoring plans shall be submitted to the Director for approval no later than February 28, 2001, as specified in paragraph 8.2.a.2 of 45CSR2.

6.1.b. Approval or denial of such plans shall be issued no later than August 31, 2001, or 6 months after submittal, whichever is later, as specified in paragraph 8.2.a.2 of 45CSR2, provided that the owner or operator may presume approval of a monitoring plan if the Director has neither approved nor denied the plan by the date specified in this subdivision.

6.1.c. Monitoring plans shall become effective upon approval.

6.2. COMS Based Monitoring Plan.

6.2.a. The owner or operator of a fuel burning unit(s) with a DHI of 250 mmBTU/hr or greater shall use a COMS to satisfy the requirements of an approved monitoring plan, except where:

6.2.a.1. The source is able to demonstrate compliance with the applicable particulate matter and opacity standards without utilization of particulate matter control equipment. Such demonstration may include, but not be limited to, Method 9 readings, stack test data, AP-42 calculations, or other data as approved by the Director.

6.2.b. The Director may exempt a source from the requirements of subdivision 6.2.a if the Director determines that the installation of a COMS would not provide an accurate determination of emissions or that the installation of a COMS may not be implemented by a source due to physical source limitations or to extreme economic reasons. The Director shall require such an exempted source to fulfill alternative emission monitoring and reporting requirements.

6.2.c. COMS, if required, shall be installed, operational and certified within twelve (12) months of the date of monitoring plan approval.

6.3. Non-COMS Based Monitoring Plan.

6.3.a. For sources not utilizing COMS as the method of monitoring compliance with the opacity limit, the approved monitoring plan shall contain at a minimum the following requirements:

6.3.a.1. Provisions to take Method 9 readings a minimum of once per month per stack during months when the source operated at normal conditions for at least twenty-four (24) consecutive hours and weather/lighting conditions were conducive to taking proper Method 9 readings;

6.3.a.2. a list of operating parameters to be monitored;

6.3.a.3. the monitoring method and frequency for each operating parameter to be monitored;

6.3.a.4. the nominal range for each operating parameter to be monitored;

6.3.a.5. an explanation of how the operating parameters to be monitored were chosen, and how they are indicative of compliance;

6.3.a.6. an explanation of how the nominal ranges were established;

6.3.a.7. a schedule for installation and operation of any additional monitoring equipment to be installed for purposes of complying with this rule; and

6.3.a.8. a response plan to be implemented during excursions which shall include, but not be limited to, the following:

6.3.a.8.A. for excursions of any operating parameter exceeding one hour, the owner or operator shall perform Method 9 readings for a minimum of six (6) minutes for each hour during the excursion. Such Method 9 readings shall continue each hour until four (4) successive six-minute observations demonstrate compliance.

6.4. In addition to other actions taken by the Director, the Director may require the monitoring plan to be revised when the Director has reason to believe that the nominal ranges established for operating parameters in the monitoring plan are no longer indicative of compliance or when the Director has reason to believe that excursions are excessive.

6.5. Notwithstanding any other provisions of this rule, the Director reserves the right to require the installation of COMS pursuant to subsection 3.2 of 45CSR2, in any case where the Director deems it necessary to determine compliance with the standards in 45CSR2.
