They regulate what vets can do on the internet, but no oversight or regulatory action against a fertilizer plant storing ammonia nitrate.
"In 2006, the Texas Commission on Environmental Quality, the primary enforcer of environmental law in the state, noted that two schools were situated within 3,000 feet of the fertilizer plant. But the agency determined that "the impact potential" of an accident on the neighboring community "was low.""
"Yet even in recent reports, state regulators saw no problems for the schools and houses nearby. For most people living near the plant, the only concern through the years was the smell of ammonia, which would periodically cause a nuisance if there were leaks in containers. Records from the Commission on Environmental Quality show several odor complaints dating back to the 1970s. But most said the smell only caused problems every few years."
