A description of any existing and planned monitoring systems that are measuring, or will measure, environmental conditions or will provide project-specific data or information on the impacts of your development and production activities.
(b) Incidental takes.
If there is reason to believe that protected species may be incidentally taken by planned development and production activities, you must describe how you will monitor for incidental take of:
(2)
Marine mammals, as appropriate, if you have not already received authorization for incidental take of marine mammals as may be necessary under the MMPA.
(c) Flower Garden Banks National Marine Sanctuary (FGBNMS).
If you propose to conduct development and production activities within the protective zones of the FGBNMS, a description of your provisions for monitoring the impacts of an oil spill on the environmentally sensitive resources of the FGBNMS.
Code of Federal Regulations
A description of the measures you took, or will take, to satisfy the conditions of lease stipulations related to your proposed development and production activities must accompany your DPP or DOCD.
(a)
If you propose to use any measures beyond those required by the regulations in this part to minimize or mitigate environmental impacts from your proposed development and production activities, a description of the measures you will use must accompany your DPP or DOCD.
(b)
If there is reason to believe that protected species may be incidentally taken by planned development and production activities, you must include mitigation measures designed to avoid or minimize that incidental take of:
(2)
Marine mammals, as appropriate, if you have not already received authorization for incidental take as may be necessary under the MMPA.
Code of Federal Regulations
A brief description of how you intend to decommission your wells, platforms, pipelines, and other facilities, and clear your site(s) must accompany your DPP or DOCD.
The following information regarding facilities and operations directly related to your proposed development and production activities must accompany your DPP or DOCD.
(a) OCS facilities and operations.
A description and location of any of the following that directly relate to your proposed development and production activities:
(3)
Right-of-way pipelines (including those that transport chemical products and produced water); and
(b) Transportation system.
A discussion of the transportation system that you will use to transport your production to shore, including:
(2)
Information concerning barges and shuttle tankers, including the storage capacity of the transport vessel(s), and the number of transfers that will take place per year;
(4)
An estimate of the quantities of oil, gas, or sulphur to be transported from your production facilities; and
The following information on the support vessels, offshore vehicles, and aircraft you will use must accompany your DPP or DOCD:
(a) General.
A description of the crew boats, supply boats, anchor handling vessels, tug boats, barges, ice management vessels, other vessels, offshore vehicles, and aircraft you will use to support your development and production activities. The description of vessels and offshore vehicles must estimate the storage capacity of their fuel tanks and the frequency of their visits to the facilities you will use to conduct your proposed development and production activities.
(b) Air emissions.
A table showing the source, composition, frequency, and duration of the air emissions likely to be generated by the support vessels, offshore vehicles, and aircraft you will use that will operate within 25 miles of the facilities you will use to conduct your proposed development and production activities.
(c) Drilling fluids and chemical products transportation.
A description of the transportation method and quantities of drilling fluids and chemical products (see § 250.243(b) and (d)) you will transport from the onshore support facilities you will use to the facilities you will use to conduct your proposed development and production activities.
(d) Solid and liquid wastes transportation.
A description of the transportation method and a brief description of the composition, quantities, and destination(s) of solid and liquid wastes (see § 250.248(a)) you will transport from the facilities you will use to conduct your proposed development and production activities.
(e) Vicinity map.
A map showing the location of your proposed development and production activities relative to the shoreline. The map must depict the primary route(s) the support vessels and aircraft will use when traveling between the onshore support facilities you will use and the facilities you will use to conduct your proposed development and production activities.
The following information on the onshore support facilities you will use must accompany your DPP or DOCD:
(a) General.
A description of the onshore facilities you will use to provide supply and service support for your proposed development and production activities (e.g., service bases and mud company docks).
(1)
Indicate whether the onshore support facilities are existing, to be constructed, or to be expanded; and
(2)
For DPPs only, provide a timetable for acquiring lands (including rights-of-way and easements) and constructing or expanding any of the onshore support facilities.
(b) Air emissions.
A description of the source, composition, frequency, and duration of the air emissions (attributable to your proposed development and production activities) likely to be generated by the onshore support facilities you will use.
(c) Unusual solid and liquid wastes.
A description of the quantity, composition, and method of disposal of any unusual solid and liquid wastes (attributable to your proposed development and production activities) likely to be generated by the onshore support facilities you will use. Unusual wastes are those wastes not specifically addressed in the relevant National Pollution Discharge Elimination System (NPDES) permit.
