I'm looking for information on Health, Safety and Environmental government regulations on businesses in the fluid processing industry here in Houston.
You may want to start with a couple of government websites. At the Federal level, the Occupational Safety and Health Administration and the Environmental Protection Agency sites may be helpful.
OSHA Laws & Regulations: http://www.osha.gov/law-regs.html
EPA Laws & Regulations: http://www2.epa.gov/laws-regulations
For state regulations, try the following.
Texas Commission on Environmental Quality: http://www.tceq.texas.gov/. Notice they have a section on business linked in the upper left corner.
Texas Department of State Health Services -Regulatory-
