OTA Environmental

OTA Environmental’s fully staffed team offers various environmental services to ensure compliance and to help navigate clients through ever-changing regulations.

What we do

This team specializes in filings done in the office, but is no stranger to the field, owning five OGI cameras to conduct LDAR surveys and other tools to help serve our clients. Our understanding of oil and gas air quality regulations, both at the state and federal level, coupled with extensive field experience and facilities and equipment knowledge, allows us to provide you with a well-rounded air quality compliance program.

Due Diligence

Phase I & II environmental site assessments, historical and regulatory file review, visual site inspections, and facility investigation/characterization.


OOOOa surveys conducted on-site with FLIR OGI cameras to detect leaks in equipment. We assist our clients in their annual submission of LDAR reports to the EPA and state regulatory agencies.

Direct Measurement Testing

A 24-hour test to determine actual emission rates from various sources (i.e. separator vent, tank vessel manifold, wellhead vent etc.), and can be quantified to determine a facility’s PTE.

GHG Reporting

Facilities that contain petroleum and natural gas systems that emit 25,000 metric tons or more of carbon dioxide equivalent per year are required to report annual greenhouse gas emissions to the EPA. We can help you determine if you are applicable to greenhouse gas (GHG) reporting.

Air Permits

State level permit required to handle vapors. If your site requires an air permit to be issued in order to authorize construction and/or operation, we can assist you in obtaining the appropriate air permit(s) for your operations.


Spill prevention, control, countermeasure plan. We help develop, maintain, and implement an oil spill prevention plan so that facilities can prevent discharge of oil in navigable waters or adjoining shorelines.

Tier II

Tier II information provides officials and the public with information on the amounts and location of hazardous chemicals.

Method 22

A simple procedure that uses the human eye to determine the total time an industrial activity causes visible emissions.


Audio, visual, and olfactory inspections. Our personnel perform careful inspection of air pollution controls and equipment and document of malfunctions and potential leaks.
