BP Oil Spill Response

US EPARolesandActivities

Situation Overview: Updated August 3, 2010

On April 22, Deepwater Horizon rig capsizes and sinks

The well was shut-in on July 15 at 2:24 p.m. No oil is flowing into the water

Pressure monitoring, visual surveillance of the seafloor, and monitoring of sonar, acoustic, and seismic data continues

About 640 miles of shoreline impacted

DHS Declared SONS

On April 29, Secretary Napolitano declares the incident a Spill of National Significance (SONS)

This designation allows the U.S. Coast Guard (USCG) to leverage the full resources available to the federal government

USCG lead federal agency EPA assisting USCG with evaluation of

environmental impacts EPA Regions 4 and 6 are integrated into single

Unified Area Command structure Area Command Post (New Orleans) Incident Command Posts (Houma, LA and

Mobile, AL)

Response to Date: Updated August 3

Total response vessels: 5,054 Total boom deployed: over 11.7 million feet (3.56M

regular plus 8.16M sorbent boom) Oily water recovered: over 826,517 barrels Dispersant used: about 1,072,514 gallons on the

surface and 771,272 gallons subsurface

Overall personnel responding: around 31,418

Dispersant Application

Dispersant use has ceased since the well was capped on July 15 – except for 200 gallons used on July 19

EPA issued Phase 2 dispersant toxicity testing results on August 2, 2010 – mixtures of oil and dispersants

USCG and EPA directives have been issued to BP EPA and USCG requiring BP to follow an adaptive

monitoring plan for subsurface application Emphasis on reducing dispersant use Surface and subsurface application is by USCG Federal

on-Scene Coordinator (FOSC) and EPA approval Requiring BP to make data public as available

Research and Development

EPA office of Research and Development (ORD) made a $2 million appropriation request for dispersant research.– Would give grants to universities with oil spill,

dispersant use and ecological risk expertise– Would focus on dispersant toxicity, application,

surface washing and bio-remediation agents and other mitigation measures

EPA Sample Locations

Air Monitoring and Air Sampling

Main objectives: monitoring for particulates, dispersant constituents, in-situ burning and evaporation by-products, air toxics, VOCs and compounds causing odors and establishing air quality baseline

Direct reading instrumentation, National Ambient Air Quality Standards (NAAQS) air monitoring network, and air toxic sampling

Special assets, Airborne Spectral Environmental Collection Technology (ASPECT) (airplane) and Trace Atmospheric Gas Analyzer (TAGA) (two mobile air sampling buses)

Monitoring and Sampling Devices

AreaRaes were used for investigating odor complaints and to establish baseline VOC data

Emergency Response Team’s (ERT) TAGA vehicle was used to obtain Volatile Organic Carbon (VOC) readings in the parts per billion range

ASPECT – aerial imagery and monitoring for shoreline and in-situ burns

Summa canisters were used to obtain air toxic information

Water Sampling Effort

Main objectives: establishing pre-spill impact sediment and water quality conditions and monitoring through impact and recovery

Using existing sample locations from EPA’s National Coastal Assessment and identified targeted locations

Special assets, coordinating with USCG and National Oceanic and Atmospheric Administration (NOAA) on deep water vessel sampling efforts and with U.S. Geological Survey (USGS) and NOAA on dispersant analyses, including aquatic toxicity

Water and Sediment Analysis

Water sampling shoreline and expanding into near-shore includes baseline and ongoing surface and sediment sampling for oil-associated contaminants and parameters related to dispersants and aquatic toxicity

– Semi-volatile (SVOC)– Metals– Total organic carbon (TOC)– Total petroleum hydrocarbons (TPH)– Dispersant constituents– Toxicity testing

Waste Management & Shoreline Cleanup

BP developed a waste management plan with EPA, states and local input

Directives were written to ensure that BP completes its responsibilities under the waste management plans.

Directives require BP to regularly report their waste management actions to EPA and USCG.

EPA Personnel Resources: Updated August 3, 2010

Region 4 has 80+ personnel in field across AL, FL, and MS, and at Regional Office in Atlanta

Total EPA and EPA contractor personnel 200-210 responding to incident, including Region 6 (Louisiana and Texas) and EPA HQ in Washington, DC.
