The Environmental Protection Agency is a regular whipping boy for Congress. In a recent response to President Reagan's weekly radio address, Sen. Frank Lautenberg, D-N.J., called the agency the "Environmental Procrastination Agency," saying that it "was, at its worst, corrupt and, at its best, timid and slow."

Last week, the EPA's regional office in Philadelphia gave Congress a dose of its own medicine. It reported that a congressionally operated power plant serving Capitol Hill is in violation of federal anti-pollution standards. The agency said that emissions exceed permissible levels when all three of the plant's boilers are running and warned that the operation should be cleaned up.

This is another in a long series of instances in which Congress demands performance by others that it doesn't of itself.
