In the game plan to clean up the air and water, monitoring is a basic tool. Without it, there are no data; with it, there is a record on which to measure progress. Requirements for ambient air and water monitoring have existed in the past; they are being strengthened, and new requirements on industrial water effluents and air emissions all point to an increase in monitoring. Last year, states, as a composite group, spent more than 1000 man-years in surveillance and told the feds that there were 6000 in-stream sampling stations. States now are faced with submitting a water quality inventory report to the EPA by January 1975. So, a basic strengthening of state water monitoring networks is under way. Monitoring of industrial effluents is required as a condition for a permit. Each industry that discharges into a navigable waterway of the U.S. will have to monitor something. The industry will also have to report both the volume to and nature of the monitored discharge. Then later, compliance monitoring—the degree of monitoring necessary to ensure that conditions of the permit are met —will be done by the states, if they elect to do it, or by the feds. Ambient air monitoring stations are required under state implementation plans. By the end of 1971 there were approximately 4000 monitors nationwide. About twice that number will be required by 1975, according to the EPA document, "National Air Monitoring Program: Air Quality and Emission Trends Annual Report," August 1973. Industrial sources, at least the new plants, need monitors too. In-stack monitors are required under new national source performance standards (NSPS). Of the five sources in the Group I NSPS, opacity, S 0 2 , and NO* monitors are required by utilities; S 0 2 monitors by sulfur acid manufacturing plants; and NO* monitors by nitric acid manufacturing plants. Of the Group 11 industries, it is anticipated that only two—petroleum refinery and basic oxygen furnace—of seven that are proposed would require in-stack monitoring; opacity monitors for BOF furnaces; and opacity, H 2 S, and CO monitors for petroleum refineries. Although such monitors are not required on existing industrial sources, someday they may well be.
