Admin. Code, Title 11, Part 2, Chapter 1, “Air Emission Regulations for the Prevention, Abatement, and Control of Air Pollutants”. (d) rendering plants, or (e) Any other new stationary source deemed by the Permit Board to be a significant minor source due to (i) the source’s potential to require significant air pollution control operations in order to avoid a violation of the Mississippi Air and Water Pollution Control Law or any regulation promulgated thereunder, (ii) the source’s potential to require significant compliance demonstration or testing requirements, (iii) the source’s potential to cause a substantial threat to public health, welfare, or the environment, or (iv) the sources’ potential to cause or substantially contribute to a violation of any applicable ambient air quality standard.

D. Permitting Requirements. (1) Permit Types. The Permit Board will issue two types of air pollution control permits, a permit to construct air emissions equipment and a State Permit to Operate such equipment. A State Permit to Operate is required for synthetic minor sources, major Title V sources, and significant minor sources. (2) Unless otherwise provided by Rule 2.13 and 2.15 or other provisions of these Regulations, any new stationary source or modification of a stationary source must have a permit to construct or multi-media permit incorporating such permit before beginning construction. (3) All applications must be submitted on the form supplied by the Permit Board and must be signed by a responsible official. (4) The Permit Board may require the applicant to submit any additional information which the Permit Board deems relevant to its decision on the permit application including, but not limited, to ambient air quality modeling. The Permit Board may require that all other media permits for a facility be issued simultaneously with any required air permit or may issue the air permit prior to or subsequent to other permits required by the facility. (5) A permit issued by the Permit Board will generally be for a specific site identified in the application. No permit application, except one for a portable facility which will be located only temporarily at a site or sites, will be processed unless the applicant controls the real property upon which the facility is located. The applicant may demonstrate control or the legal right to operate through ownership, lease, eminent domain, easement, license and/or contract. For portable facilities which will be located only temporarily at a site or sites, the Permit Board may issue a statewide permit or a permit for operation in multiple areas. (6) It is the responsibility of the applicant/permittee to obtain all other approvals, permits, clearances, easements, agreements, etc., which may be required including, but not limited to, all required local government zoning approvals or permits. DEQ may delay processing any permit application until the applicant provides to DEQ information or documentation sufficient to demonstrate any approval listed in this paragraph. (7) The provisions of a permit are severable. If any provision of a permit, or the application of any provision of a permit to any circumstances, is challenged or held invalid, the validity of the remaining permit provisions and/or portions thereof or their application to other persons or sets of circumstances, shall not be affected thereby. (8) In the event of a conflict between any of the requirements of these regulations and/or applicable requirements of any other regulation or law, the more stringent requirements shall be applied. (9) A stationary source which emits or causes to be emitted matter other than through a stack or a defined outlet of an air cleaning device may be classified inadequate in regard to control equipment. Facilities which comply with emission standards which specifically address and include fugitive emissions shall be presumed adequate provided all other Applicable Rules and Regulations are complied with.
