NESHAPs Exercise:
Scenario: You are an environmental engineer working for an oil and gas company. Your company is planning to expand its operations, and you need to ensure compliance with NESHAPs.
Task:
- Research the specific NESHAP regulations that apply to your company's operations. Consider the type of operations (production, processing, storage, etc.) and the specific pollutants that may be emitted.
- Identify potential emission sources within the expansion project.
- Develop a plan to control emissions from these sources, taking into account existing and potential control technologies.
- Outline a monitoring and reporting plan to ensure compliance with NESHAPs.
Exercice Correction
This exercise requires specific research and analysis based on the company's operations and location. A successful answer would include the following steps:
- Research: Identify the specific NESHAP Subpart applicable to the company's operation (e.g., Subpart W for oil and natural gas production, Subpart KKK for natural gas processing plants). Review the emission standards and requirements outlined in the Subpart.
- Emission Source Identification: Analyze the expansion project and identify potential sources of HAP emissions, such as well completions, storage tanks, or processing units. Consider potential emissions from equipment leaks, venting, and flaring.
- Control Technology Selection: Develop a plan to control emissions from identified sources. This might involve using:
- Vapor recovery systems to capture and reuse volatile organic compounds (VOCs)
- Leak detection and repair (LDAR) programs to minimize leaks from equipment
- Flares (with appropriate controls) for emergency releases or process venting
- Other technologies like combustion control or pollution prevention techniques
- Monitoring and Reporting Plan: Establish a system to monitor emissions from the identified sources. This might involve:
- Continuous monitoring of specific pollutants
- Periodic inspections and sampling to verify control equipment efficiency
- Record-keeping and reporting to the EPA as required by the specific NESHAP Subpart
The specific details of the plan would depend on the company's operations, location, and the regulations that apply. It is crucial to consult with environmental experts and refer to the EPA's website for up-to-date information on NESHAP requirements.
