La. Admin. Code tit. 33 § IX-4769

Current through Register Vol. 50, No. 6, June 20, 2024
Section IX-4769 - As an owner or operator of a new offshore oil and gas extraction facility, what must I do to comply with this Subchapter?
A. Applicability
1. The owner or operator of a new offshore oil and gas extraction facility must comply with:
a. the Track I requirements in Subsection B or the Track II requirements in Subsection C of this Section, if it is a fixed facility; or
b. the T rack I requirements in Subsection B of this Section, if it is not a fixed facility.
2. In addition to meeting the requirements in Subsection B or C of this Section, the owner or operator of a new offshore oil and gas extraction facility may be required to comply with Subsection D of this Section.
B. Track I Requirements for New Offshore Oil and Gas Extraction Facilities
1. New offshore oil and gas extraction facilities that are fixed facilities shall:
a. comply with all of the requirements in Paragraphs B.3-9 of this Section if they do not employ sea chests as cooling water intake structures; or
b. comply with the requirements in Paragraphs B.3, 4, 5, 7, 8, and 9 of this Section if they employ sea chests.
2. New offshore oil and gas extraction facilities that are not fixed facilities must comply with the requirements in Paragraphs B.3, 5, 7, 8, and 9 of this Section.
3. You must design and construct each cooling water intake structure at your facility to a maximum through-screen design intake velocity of 0.5 ft/ s.
4. For cooling water intake structures located in an estuary or tidal river, the total design intake flow over one tidal cycle of ebb and flow must be no greater than 1 percent of the volume of the water column within the area centered about the opening of the intake with a diameter defined by the distance of one tidal excursion at the mean low water level.
5. You must select and implement design and construction technologies or operational measures for minimizing impingement mortality of fish and shellfish if the administrative authority determines that:
a. there are threatened or endangered or otherwise protected federal, state, or tribal species, or critical habitat for these species, within the hydraulic zone of influence of the cooling water intake structure; or
b. based on information submitted by any fishery management agency or other relevant information, there are migratory and/ or sport or commercial species of impingement concern to the administrative authority that pass through the hydraulic zone of influence of the cooling water intake structure; or
c. based on information submitted by any fishery management agency or other relevant information, the proposed facility, after meeting the technology-based performance requirements in Paragraphs B.3 and 6 of this Section, would still contribute unacceptable stress to the protected species, or critical habitat of those species, or species of concern.
6. You must select and implement design and construction technologies or operational measures for minimizing entrainment of entrainable life stages of fish and shellfish.
7. You must submit the applicable application information required in LAC 33:IX.2501.R and 4773.B. If you are a fixed facility, you must submit the information required in LAC 33:IX.2501.R.2 (except 2.d), 3, and 4 and 4773.B as part of your application. If you are a not a fixed facility, you must only submit the information required in LAC 33:IX.2501.R.2.d and 3 (except 3.b) and 4773.B as part of your application.
8. You must implement the monitoring requirements specified in LAC 33:IX.4775.
9. You must implement the recordkeeping requirements specified in LAC 33:IX.4777.
C. Track II Requirements for New Offshore Oil and Gas Extraction Facilities. The owner or operator of a new offshore oil and gas extraction facility that is a fixed facility and chooses to comply under Track II must comply with the following requirements.
1. You must demonstrate to the administrative authority that the technologies employed will reduce the level of adverse environmental impact from your cooling water intake structures to a comparable level to that which you would achieve were you to implement the applicable requirements of Paragraph B.3 of this Section and, if your facility is a fixed facility without a sea chest, also Paragraph B.6 of this Section. This demonstration must include a showing that the impacts to fish and shellfish, including important forage and predator species, will be comparable to those which would result if you were to implement the requirements of Paragraph B.3 of this Section and, if your facility is a fixed facility without a sea chest, also Paragraph B.6 of this Section. In identifying such species, the administrative authority may consider information provided by any fishery management agency along with data and information from other sources.
2. For cooling water intake structures located in an estuary or tidal river, the total design intake flow over one tidal cycle of ebb and flow must be no greater than 1 percent of the volume of the water column within the area centered about the opening of the intake with a diameter defined by the distance of one tidal excursion at the mean low water level.
3. You must submit the applicable information required in LAC 33:IX.2501.R.2 (except 2.d), 3, and 4 and 4773.C.
4. You must implement the monitoring requirements specified in LAC 33:IX.4775.
5. You must implement the recordkeeping requirements specified in LAC 33:IX.4777.
D. You must comply with any more stringent requirements relating to the location, design, construction, and capacity of a cooling water intake structure or monitoring requirements at a new offshore oil and gas extraction facility that the administrative authority deems are reasonably necessary to comply with any provision of federal or state law, including compliance with applicable state water quality standards (including designated uses, criteria, and antidegradation requirements).
