Two older factory workers were discussing the government regulations that limit how they can dispose of their factory's wastes. One worker notes, You know, we didn't use to have all these regulations.
 
  In fact, there were almost no regulations controlling what we could put in the air, water, or underground before the A) 1990s and the beginning of OSHA.
  B) 1980s and the beginning of SARA.
  C) 1970s and the beginning of the CAA and CWA.
  D) 1960s and the beginning of the EPA.

Question 2

A small city's sewage-treatment plant orders a 55-gallon drum of isopropyl alcohol to be used to prepare cleaning products. However, when the drum arrives, it contains methyl alcohol, which they cannot use.
 
  The manager says to reorder and get the correct alcohol. The workers wonder what to do with the unusable 55 gallons of methyl alcohol that arrived by mistake. Someone suggests just dumping it into the nearby stream. Another worker disagrees, noting that to legally dispose of the 55 gallons of methyl alcohol, they need to A) dump the alcohol into their sewage treatment tanks, which then drain into the stream.
  B) mix the alcohol with gasoline to make it safer, and then dump it into the stream.
  C) get a discharge permit, mandated under the CWA, to allow them to dump it into the stream.
  D) flush the alcohol into the stream using thousands of gallons of water to dilute it.
