§550.249. What air emissions information must accompany the DPP or DOCD? — Inbound Citations

(g) Air emissions information required by § 550.249;

(2) For a facility identified by the Regional Supervisor in paragraph (b)(1) of this section, the Regional Supervisor shall require the lessee to refer to the information required in § 550.218 or § 550.249 of this part and to submit only that information required to make the necessary findings under paragraphs (d) through (i) of this section. The lessee shall submit this information within 120 days of the Regional Supervisor's determination or within a longer period of time at the discretion of the Regional Supervisor. The lessee shall comply with the requirements of this section as necessary.

(6) If the Regional Supervisor determines that an existing facility has the potential to significantly affect the air quality of an onshore area of the State submitting information under paragraph (a)(3) of this section, the Regional Supervisor shall require the lessee to refer to the information requirements under § 550.218 or § 550.249 of this part and submit only that information required to make the necessary findings under paragraphs (b) through (e) of this section. The lessee shall submit this information within 120 days of the Regional Supervisor's determination or within a longer period of time at the discretion of the Regional Supervisor. The lessee shall comply with the requirements of this section as necessary.

(a) Exploration, testing, development, production, and processing activities proposed to be conducted under a lease will only be approved by the Director upon the determination that the adverse impacts of the proposed activities can be avoided, minimized, or otherwise mitigated. The Director shall take into account the information contained in the sale-specific environmental evaluation prepared in association with the lease offering as well as the site- and operational-specific environmental evaluations prepared in association with the review and evaluation of the approved Delineation, Testing, or Mining Plan. The Director's review of the air quality consequences of proposed OCS activities will follow the practices and procedures specified in 30 CFR 250.194, §§ 550.194, 550.218, 550.249, and 550.303.

(d) To determine whether a facility described in an initial, modified, supplemental, or revised Exploration Plan, Development and Production Plan, or Development Operations Coordination Document is exempt from further air quality review, the lessee must use the highest annual-total amount of emissions from the facility calculated for each criteria air pollutant, VOC, and TSP listed in § 550.249(a) or § 550.218(a) and compare these emissions to the emission exemption threshold (EET) calculated using the following formulas: EET = 3400D2/3 for carbon monoxide (CO); and EET = 33.3D for total suspended particulates (TSP), sulfur dioxide (SO2), nitrogen oxides (NOX), utilizing NO2 as the indicator pollutant for NOX, and VOC (where EET is the emission exemption threshold expressed in short tons per year, and D is the distance of the proposed facility from the closest onshore area of a State expressed in statute miles). If the amount of these projected emissions is less than or equal to the emission exemption threshold (EET) for the corresponding criteria air pollutant, VOC, and TSP, the facility is exempt from further air quality review required under paragraphs (e) through (i) of this section.

(b) To determine whether an existing facility is exempt from further air quality review, the lessee must use the highest annual-total amount of emissions from the facility calculated for each criteria air pollutant, VOC, and TSP listed in § 550.249(a) or § 550.218(a) and compare these emissions to the emission exemption threshold (EET) calculated using the following formulas: EET = 3400D2/3 for carbon monoxide (CO); and EET = 33.3D for total suspended particulates (TSP), sulfur dioxide (SO2), nitrogen oxides (NOX), utilizing NO2 as the indicator pollutant for NOX and VOC (where EET is the emission exemption threshold expressed in short tons per year, and D is the distance of the proposed facility from the closest onshore area of a State expressed in statute miles). If the amount of these projected emissions is less than or equal to the emission exemption threshold (EET) for the corresponding criteria air pollutant, VOC, and TSP, the facility is exempt from further air quality review required under paragraphs (c) through (e) of this section.
