West Virginia Code of State Rules › Agency 45 - Air Quality › Title 45 - LEGISLATIVE RULE DEPARTMENT OF ENVIRONMENTAL PROTECTION AIR QUALITY › Series 45-10 - To Prevent And Control Air Pollution from the Emission Of Sulfur Oxides › Section 45-10-5 - Combustion of Refinery or Process Gas Streams

Current through Register Vol. XLI, No. 28, July 12, 2024
5.1. No person
				shall cause, suffer, allow or permit the combustion of any refinery process gas
				stream or any other process gas stream that contains hydrogen sulfide in a
				concentration greater than 50 grains per 100 cubic feet of gas except in the
				case of a person operating in compliance with an emission control and
				mitigation plan approved by the Secretary and U. S. EPA. In certain cases very
				small units may be considered exempt from this requirement if, in the opinion
				of the Secretary, compliance would be economically unreasonable and if the
				contribution of the unit to the surrounding air quality could be considered
				negligible.
5.2. Any owner or
				operator of a by-product coke production facility in existence on August 31,
				2000 who can demonstrate to the Secretary that there is no practical
				alternative to scheduled maintenance (including shutdown) of desulfurization
				equipment may request the approval of an enforceable, temporary sulfur dioxide
				emissions control and mitigation plan for such maintenance period. In order for
				a plan under this subsection to be approved the plan must meet the following
				conditions:
5.2.1. Provide that all feasible
				control measures and process changes will be employed at the coke production
				facility to reduce emissions of sulfur dioxide (including reduction of coke
				oven gas generation) during the control system outage.
5.2.2. Provide for a definitive reduction in
				sulfur dioxide emissions by the establishment of unit-specific allowable
				emission rates for all emissions units of the stationary source sufficient to
				prevent any violation of federal and state ambient air quality standards or
				applicable air quality increments for sulfur dioxide.
5.2.3. Provide that system down-time and
				excess sulfur dioxide emissions be reduced to the greatest extent possible by
				use of increased or contract maintenance personnel, maximized maintenance labor
				shifts and optimization of available spare parts inventories.
5.2.4. Provide for emissions and compliance
				monitoring as required by the Secretary in the approved plan during the
				maintenance periods and for the submission of reports of such monitoring and
				tests within time-frames specified by the Secretary in the approved plan. All
				approved plans shall require that a certified report of excess sulfur dioxide
				emissions from the by-product coke production facility and offsetting emission
				units be submitted to the Secretary within 30 days after the end of the
				maintenance period.
5.2.5. Provide
				that no maintenance period exceed 14 days in length nor occur more than twice
				in any calendar year.
5.2.6.
				Provide at least two weeks notice of all scheduled maintenance periods, the
				anticipated length of the maintenance period, work to be completed, measures to
				be taken to minimize the length of desulfurization system down-time and such
				other information as the Secretary may specify.
5.2.7. Provide for annual review, if
				necessary, modification or termination of the plan by the Secretary.
5.2.8. Provide that the Secretary may impose
				limitations on emission units that are more restrictive than those provided for
				in the plan as necessary to assure attainment of air quality standards for
				sulfur dioxide in light of data provided pursuant to subdivision 5.2.6, or any
				other information available to the Secretary.
