On March 26, the North Carolina League of Conservation Voters and the Gulf Future Coalition held a conference call on which people of the Gulf Coast talked about what Atlantic Coast residents can expect if the proposal to allow offshore drilling in the Atlantic from Virginia to Georgia wins federal approval.

Among those who spoke was Wilma Subra, an environmental scientist based in Louisiana and a technical adviser for the Louisiana Environmental Action Network. She has won numerous accolades for her work helping communities affected by the oil and gas industry, including a MacArthur "Genius Grant" and a Global Exchange Human Rights Award.

Subra described in detail the environmental impacts that Southeastern Atlantic Coast residents would face from offshore oil and gas development and the associated industrialization of the region. We are sharing her prepared remarks in full, edited only to fix typos and other minor details.

The U.S. Bureau of Ocean Energy Management is accepting comments on the proposal through Monday, March 30. For details on how to share comments, click here. Subra can be reached at subracom@aol.com.

Coastal Conversation: Mid-Atlantic States - Impacts of Offshore Drilling

By Wilma Subra, Subra Company

Offshore exploration, drilling and production will produce large quantities of oil and natural gas resources and has the potential to result in an economic boom to the coastal states along the Atlantic Ocean.

However, along with the economic aspects, huge permanent environmental damage and destruction will occur over the short and long term.

Exploration, drilling and production in the offshore area will result in:

* contamination of offshore waters

* disruption of the sea bed including clearing of the seabed, cracks, fissures and hydrocarbon seeps

* produced water/saltwater leaks and spills of high salt content fluids (much higher than ocean water) containing heavy metals, petroleum hydrocarbons and radioactive components that will disrupt, damage and destroy the aquatic and benthic organisms in the water column and bottom sediments of the offshore environment.

Spills and leaks of hydrocarbons and toxic heavy metals will occur from the drilling and production rigs and the boats servicing the rigs. Hundreds of spills and leaks occur on a daily basis in the offshore area of the Gulf of Mexico.

Changes in the offshore environment will occur due to the presence and activities occurring on each of the rigs:

* Physical and chemical-based negative impacts to marine ecosystems

* Disruption of the seabed in the area of the rig footprint

* Bioaccumulation of toxic substances from the drilling and production activities into the marine environment

* Air and water pollution from the equipment on the rigs and on the vessels servicing the rigs, flares burning and releasing large quantities of air emissions of unburned hydrocarbons and products of incomplete combustion.

Pipeline Networks

A network of pipelines [is] required to connect the rigs to the mainland for the transportation of oil and gas resources and in some cases, waste products.

The pipelines disrupt the sea bottom ecosystems, physical and structural integrity of the sea bottom, and water flow patterns.

As the pipelines travel through the estuaries and on land, their transportation routes are heavily damaged. The physical and structural disruption of the environment becomes even greater. Marshlands and wetlands are disrupted and begin to erode and the coastline moves inland.

The offshore and coastal areas will be forever damaged and destroyed.

Waste Generated by Exploration, Drilling and Production of Oil and Gas

In the offshore area the following types of waste will be generated in large quantities due to exploration, drilling and production of oil and gas:

* Produced water

* Drill cuttings

* Oil- and water-based drilling muds

* Drilling fluids

* Production formation oily sands and solids

* Deck drainage

* Well treatment, completion and workover fluids

* Tank bottoms and sludges

* Naturally occurring radioactive waste

Onshore Waste Management, Treatment and Disposal Facilities to Handle the Generated Oil and Gas Waste Streams

Class II injection wells dispose of:

* produced water

* flowback water and fracturing fluids

* waste streams completion, workover and stimulation fluids

* washout water

* pipeline test water

* crude oil spill clean-up waste

Land farms for solid and semi-solid waste streams

Landfills for solid and semi-solid waste streams and solidified liquid
waste streams

Physical and chemical treating facilities

Oil and gas waste recycling facilities

Naturally occurring radioactive materials treatment and disposal facilities

Processing facilities for the oil and gas brought onshore in pipelines and vessels

Natural gas processing plants

* Sweeten the gas streams to reduce the sulfur content and dry the gas to remove the moisture. The glycol dehydration units at gas processing plants release very large quantities of benzene, a known human cancer-causing agent.

Crude oil separation facilities

* Remove the produced water portion of production and production sands from the crude oil.

Crude oil storage, processing and distribution facilities

* There are large quantities of waste streams generated from these processing facilities, including air emissions released and flared from the facilities, process wastewater discharged from the facilities and solids and semi-solid waste streams.

Other Infrastructure

Shipyards

* Construct rig superstructure, oceangoing service vessels and rig equipment.

Service companies

* Provide wireline services, fracking equipment and services, anchor mechanisms, drilling muds and chemicals, generators, and a whole host of equipment needed by the offshore rigs.

Conclusions

These are just a few of the environmental impacts offshore and onshore that will result when offshore exploration, drilling and production comes into an area.

To connect the produced resources to end users in the United States and other countries, pipeline networks will be required to be established, [and] liquefied natural gas export facilities may be proposed along the coastal areas to export liquefied natural gas to free trade and non-free trade countries.

Industrial facilities such as gas to liquid facilities may want to locate in the area to take advantage of the abundant quantity of natural gas.

Storage tank terminals will spring up to store and supply the crude oil produced off shore.

Rail lines and loop systems may be constructed to ship the produced crude by rail to areas not adequately serviced by pipelines.

Many of these facilities may be targeted for locations in environmental justice communities as well as in residential, recreational and nature preserves based on physical locations to connect to existing infrastructure.

The physical environment will be severely negatively impacted, in the name of progress and [with] little to no consideration of the impacts.
