Virginia Department of Health Letter of Health Consultation

The Virginia Department of Health (VDH) has released its letter of health consultation for the Buckingham Compressor Station air permit.

State Air Pollution Control Board Approves BCS Permit

On January 8, 2019, the State Air Pollution Control Board (SAPCB) voted unanimously to approve the Buckingham Compressor Station (BCS) minor new source review air permit. The permit was signed and issued to Dominion Energy on January 9, 2019.

Signed Permit and Analysis


In September 2015, ACP submitted an air permit application for proposed construction and operation of a natural gas-fired compressor station in Buckingham County, Virginia (Buckingham Compressor Station or BCS) 1.5 miles northwest of the intersection of Route 60 and Route 56. After submittal of the original application, ACP made significant design changes to the project. These changes, in addition to additional information requested by DEQ resulted in a revised application being submitted in May 2018. Following this submittal, DEQ requested further information and the application was finally deemed complete in July 2018. All the information received was used in the development of the draft permit which was subject to public comment.

The draft permit is a minor new source review (NSR) permit. For a compressor station to be classified as a major source under NSR, it must have the potential to emit greater than 250 tons per year (tpy) of any regulated NSR pollutant. All the emissions at the BCS will be well below major NSR permit levels with the highest permitted emissions for any pollutant being 43 tpy for particulate matter. DEQ required a thorough Best Available Control Technology (BACT) analysis, air quality dispersion modeling and held a public comment period including a public hearing.


Part of DEQ’s process in developing the permit for the BCS included a comprehensive review of permits for other compressor stations across the United States. Based on the information available at the time of this review, the requirements established in this draft permit make BCS the most stringently controlled compressor station in Virginia and in the United States. The pollutant limits and monitoring requirements in the BCS draft permit are more restrictive than the permits already issued by West Virginia and North Carolina for two similar stations to be located along the ACP.

DEQ required an air quality modeling analysis to demonstrate compliance with the health-based concentrations called National Ambient Air Quality Standards (NAAQS). In addition, DEQ required the facility to conduct a modeling analysis for specific toxic air pollutants in order to ensure the concentrations would be below the Virginia Significant Ambient Air Concentrations (SAAC). The results of these analyses demonstrate that the facility will not cause any exceedances of regulatory health-based standards.

Additional Information on Frequently Asked Questions Not Covered by the Air Permit

DEQ has limited authority under its regulations and often receives questions which fall outside of the purview of the State Air Pollution Control Board Statute and Regulations. DEQ understands the importance of these issues to the citizens who live and work in the community surrounding the proposed facility. DEQ has identified some of the frequently asked questions and the following information should be helpful in answering some of those questions.

Site Zoning – The Buckingham County Board of Supervisors approved the Special Use Permit (SUP) for the siting of the facility on January 5, 2017. Buckingham County Board of Supervisors meeting minutes are available on the Buckingham County website.

Noise – The Buckingham County SUP limits noise at the property boundary both during construction and during operation of the facility. Noise is addressed in conditions 5, 6 and 18 of the SUP. Additional information regarding the BCS construction and noise control is available on the ACP website.

Light – The Buckingham County SUP limits light at the property boundary. The SUP lighting requirements can be found in conditions 8, 9, and 10.

Traffic – The Buckingham County SUP addresses the issue of traffic in condition 20.

Worker SafetyThe Occupational Safety and Health Administration (OSHA) regulates workplace safety. OSHA programs apply to employer and employee.

Community Safety – Emergency preparedness and response is covered by the Pipeline and Hazardous Materials Safety Administration (PHMSA) and the U.S. Department of Transportation. Additionally the Buckingham County SUP addresses emergency issues, including fire, in conditions 4, 35, 36 and 40.

Facility Need – The need for a utility line such as the Atlantic Coast Pipeline, and therefore the BCS, is reviewed and approved by the federal government’s Federal Energy Regulatory Commission (FERC).
