Petrol Corp. owns several drilling operations in the Gulf of Mexico, refineries, service stations, and tanker trucks for transporting their products. Petrol Corp. hires an environmental manager to keep the company in compliance with various environmental laws. What laws will the environmental manager need to study and why?

The environmental manager will need to study the Clean Air Act because the refineries and tanker trucks would be regulated by the Act. She would also need to study the Clean Water Act. The refineries and drilling operations may be located near or affect navigable waters, tributaries of navigable waters, interstate waters and their tributaries, non-navigable intrastate waters, and freshwater wetlands.
The Toxic Substances Control Act would be another Act the manager would need to review. The refineries may be using additives that are toxic substances, and the petroleum is also a toxic substance. The refineries, service stations, and drilling operations produce hazardous waste in connection with the petroleum producing activities. Therefore, RCRA would need to be reviewed to assess the plant's operations as well. In addition, the manager will have to review any state and local air, water, or waste disposal statutes or ordinances.
