Prevention of Accidental Releases-Section 112(r)[15A NCAC 02Q.0508(h)] If the Permittee is required to develop and register a Risk Management Plan with EPA pursuant to Section 112(r)of the Clean Air Act,then the Permittee is required to register this plan in accordance with 40 CFR Part 68. EE. Prevention of Accidental Releases General Duty Clause-Section 112(r)(1)—FEDERALLY-ENFORCEABLE ONLY Although a risk management plan may not be required,if the Permittee produces,processes,handles,or stores any amount of a listed hazardous substance,the Permittee has a general duty to take such steps as are necessary to prevent the accidental release of such substance and to minimize the consequences of any release. Air Quality Permit 09492T09 Page 18 FF. Title IV Allowances[15A NCAC 02Q.0508(i)(1)] This permit does not limit the number of Title IV allowances held by the Permittee,but the Permittee may not use allowances as a defense to noncompliance with any other applicable requirement. The Permittee's emissions may not exceed any allowances that the facility lawfully holds under Title IV of the Federal Clean Air Act. GG. Air Pollution Emergency Episode[15A NCAC 02D.0300] Should the Director of the DAQ declare an Air Pollution Emergency Episode,the Permittee will be required to operate in accordance with the Permittee's previously approved Emission Reduction Plan or,in the absence of an approved plan,with the appropriate requirements specified in 15A NCAC 02D.0300. HH. Registration of Air Pollution Sources[15A NCAC 02D.0202] The Director of the DAQ may require the Permittee to register a source of air pollution. If the Permittee is required to register a source of air pollution,this registration and required information will be in accordance with 15A NCAC 02D .0202(b). II. Ambient Air Quality Standards[15A NCAC 02D.0501(c)] In addition to any control or manner of operation necessary to meet emission standards specified in this permit,any source of air pollution shall be operated with such control or in such manner that the source shall not cause the ambient air quality standards in 15A NCAC 02D.0400 to be exceeded at any point beyond the premises on which the source is located. When controls more stringent than named in the applicable emission standards in this permit are required to prevent violation of the ambient air quality standards or are required to create an offset,the permit shall contain a condition requiring these controls. JJ. General Emissions Testing and Reporting Requirements[15A NCAC 02Q.0508(i)(16)] Emission compliance testing shall be by the procedures of Section.2600,except as may be otherwise required in Rules .0524, .0912, .1110, .1111,or.1415 of Subchapter 02D. If emissions testing is required by this pen-nit or the DAQ or if the Permittee submits emissions testing to the DAQ to demonstrate compliance,the Permittee shall perform such testing in accordance with 15A NCAC 02D.2600 and follow the procedures outlined below: 1. The owner or operator of the source shall arrange for air emission testing protocols to be provided to the Director prior to air pollution testing.Testing protocols are not required to be pre-approved by the Director prior to air pollution testing.The Director shall review air emission testing protocols for pre-approval prior to testing if requested by the owner or operator at least 45 days before conducting the test. 2. Any person proposing to conduct an emissions test to demonstrate compliance with an applicable standard shall notify the Director at least 15 days before beginning the test so that the Director may at his option observe the test. 3. The owner or operator of the source shall arrange for controlling and measuring the production rates during the period of air testing.The owner or operator of the source shall ensure that the equipment or process being tested is operated at the production rate that best fulfills the purpose of the test. The individual conducting the emission test shall describe the procedures used to obtain accurate process data and include in the test report the average production rates determined during each testing period. 4. Two copies of the final air emission test report shall be submitted to the Director not later than 30 days after sample collection unless otherwise specified in the specific conditions. The owner or operator may request an extension to submit the final test report.The Director shall approve an extension request if he finds that the extension request is a result of actions beyond the control of the owner or operator. a. The Director shall make the final determination regarding any testing procedure deviation and the validity of the compliance test.The Director may: i. Allow deviations from a method specified under a rule in this Section if the owner or operator of the source being tested demonstrates to the satisfaction of the Director that the specified method is inappropriate for the source being tested. ii. Prescribe alternate test procedures on an individual basis when he finds that the alternative method is necessary to secure more reliable test data. iii. Prescribe or approve methods on an individual basis for sources or pollutants for which no test method is specified in this Section if the methods can be demonstrated to determine compliance of permitted emission sources or pollutants. b. The Director may authorize the Division of Air Quality to conduct independent tests of any source subject to a rule in this Subchapter to determine the compliance status of that source or to verify any test data submitted relating to that source.Any test conducted by the Division of Air Quality using the appropriate testing procedures described in Section 02D.2600 has precedence over all other tests. Air Quality Permit 09492T09 Page 19 KK. Reopenin2 for Cause[15A NCAC 02Q.0517] 1. A permit shall be reopened and revised under the following circumstances: a. additional applicable requirements become applicable to a facility with remaining permit term of three or more years; b. additional requirements(including excess emission requirements)become applicable to a source covered by Title IV; c. the Director or EPA finds that the permit contains a material mistake or that inaccurate statements were made in establishing the emissions standards or other terms or conditions of the permit;or d. the Director or EPA determines that the permit must be revised or revoked to assure compliance with the applicable requirements. 2. Any permit reopening shall be completed or a revised permit issued within 18 months after the applicable requirement is promulgated. No reopening is required if the effective date of the requirement is after the expiration of the permit term unless the term of the permit was extended pursuant to 15A NCAC 02Q.0513(c). 3. Except for the state-enforceable only portion of the permit,the procedures set out in 15A NCAC 02Q.0507,.0521,or .0522 shall be followed to reissue the permit. If the State-enforceable only portion of the permit is reopened,the procedures in 15A NCAC 02Q.0300 shall be followed. The proceedings shall affect only those parts of the permit for which cause to reopen exists. 4. The Director shall notify the Permittee at least 60 days in advance of the date that the pen-nit is to be reopened,except in cases of imminent threat to public health or safety the notification period may be less than 60 days. 5. Within 90 days,or 180 days if the EPA extends the response period,after receiving notification from the EPA that a permit needs to be terminated,modified,or revoked and reissued,the Director shall send to the EPA a proposed determination of termination,modification,or revocation and reissuance,as appropriate. LL. Reportine Requirements for Non-Operating Equipment[15A NCAC 02Q.0508(i)(16)] The Pemuttee shall maintain a record of operation for permitted equipment noting whenever the equipment is taken from and placed into operation.
