N.M. Admin. Code § 20.11.61.11

Current through Register Vol. 35, No. 20, October 22, 2024

Section 20.11.61.11 - APPLICABILITY

A. The requirements of 20.11.61 NMAC apply to the construction of any new major stationary source or any project at an existing major stationary source in an area designated as attainment or unclassifiable.

B. The requirements of 20.11.61.12 NMAC through 20.11.61.18NMAC, 20.11.61.21 NMAC and 20.11.61.24 NMAC apply to the construction of any new major stationary source or the major modification of any existing major stationary source except as 20.11.61 NMAC otherwise provides.

C. No new major stationary source or major modification to which the requirements of Subsections A, B, C, and D of 20.11.61.12 NMAC, 20.11.61.13 NMAC through 20.11.61.18 NMAC, 20.11.61.21 NMAC and 20.11.61.24 NMAC apply shall begin actual construction without a permit that states that the major stationary source or major modification will meet those requirements.

D. Applicability procedures.

(1) Except as otherwise provided in Subsection E of 20.11.61.11 NMAC, and consistent with the definition of major modification, a project is a major modification for a regulated NSR pollutant if it causes a significant emissions increase and a significant net emissions increase. The project is not a major modification if it does not cause a significant emissions increase. If the project causes a significant emissions increase, then the project is a major modification only if it also results in a significant net emissions increase.

(2) The procedure for calculating (before beginning actual construction) whether a significant emissions increase (i.e., the first step of the process) will occur depends upon the type of emissions units being modified, according to Paragraphs (3) through (5) of Subsection D of 20.11.61.11 NMAC. The procedure for calculating (before beginning actual construction) whether a significant net emissions increase will occur at the major stationary source (i.e., the second step of the process) is contained in the definition in Subsection PP of 20.11.61.7 NMAC. Regardless of any such preconstruction projections, a major modification results if the project causes a significant emissions increase and a significant net emissions increase.

(3) Actual-to-projected-actual applicability test for projects that only involve existing emissions units. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the projected actual emissions and the baseline actual emissions for each existing emissions unit equals or exceeds the significant amount for that pollutant.

(4) Actual-to-potential test for projects that only involve construction of a new emissions unit(s). A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the potential to emit from each new emissions unit following completion of the project and the baseline actual emissions of these units before the project equals or exceeds the significant amount for that pollutant.

(5) Hybrid test for projects that involve multiple types of emissions units. A significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the emissions increases for each emissions unit, using the method specified in Paragraphs (3) and (4) of Subsection D of 20.11.61.11 NMAC as applicable with respect to each emissions unit, for each type of emissions unit equals or exceeds the significant amount for that pollutant.

E. For any major stationary source for a PAL for a regulated NSR pollutant, the major stationary source shall comply with requirements under 20.11.61.20 NMAC.
