586 MINERALS YEARBOOK, 1972 loading terminal coi~trols, sulfur recovery facilities, process and equipment modifications, and combustion controls. When completed, the program was expected to eliminate the annual emissions of 7,320 tons of hydrocarbons, 9,835 tons of sulfur dioxide, and 9,540 tons of carbon monoxide. Allegheny County was foremost in the State's pollution news and activities. The Allegheny County Health Department (ACHD) operated 49 air-monitoring stations that indicated an overall 8% decrease in particulate levels and a 33% decrease in sulfur dioxide levels compared with the 1971 overall levels. ACHD's plans were directed to achieve EPA primary air quality standards by 1975. Interim measures planned for 1973 included a survey of area plants to identify emissions and to develop programs for compliance with ACHD's new air pollution standarch, the annual review and issuance of permits for air pollution sources, and the relocation of the Courthouse monitoring station accompanied by the addition of devices for measuring nitrogen oxides, ozone, and hydrocarbons. ACHD's new air pollution code, effective June 15, was more stringent than the 1970 code. Sulfur dioxide limits were lowered another 60% to 75%.; 90% of the sulfur had to be removed from coke oven gas; the number of blast furnace slips was limited; and the limit on particulates emitted from powerplants, steel plants, and iron foundries was lowered. Smoke limits were reduced 50%, and Ringelmann No. 3 or darker was classed as a violation at any time. The DER's Division of Mine Drainage and Erosion issued 23 water permits to operators of underground bituminous coal, limestone, and clay mines. A 500,000-gallon-per-day (gpd) mine wastewater treatment plant was completed in Indiana County. The water treatment, based on the relatively new Desal process developed by the Rohm and Haas Co., used an ion-exchange resin capable of operation in the presence of bicarbonates. The aqueous effluent was aerated to precipitate iron and manganese. The total cost for treating a typical acidic mine water containing 1,000 parts per million (ppm) iron was estimated at about 30 cents per 1,000 gallons.7 The Burgettstown demineralization plant operated by the Smith Township Municipal Authority was described.8 A 3-day program relating to the control of water pollution from coal mining was held at Penn State October 4 through 6. Included were discussions on preventing and minimizing drainage formation, treatment procedures, and governmental regulations. The Fourth Symposium on Coal Mine Drainage Research was held April 27 at the Mellon Institute in Pittsburgh. More than 400 attendees heard 32 technical papers on the remaining problems and emerging answers of mine drainage control. The biennial symposium was organized by Bituminous Coal Research, Inc. (BCR), Monroeville, with program planning help from EPA, DER, and the Ohio River Valley Sanitation Commission (ORANSCO). Solid Wastes.—The EPA approved a $103,000 grant in November for a 6-month study of the feasibility of moving refuse from Philadelphia by railroad to abandoned anthracite strip mine pits. If the idea appears practical, Philadelphia will be eligible for a $551,000 EPA grant to complete the plan, which hopefully would be operable in June 1974. DER denied Lycoming County's application to use a bituminous coal strip mine in Cogan House Township for landfill purposes. The denial was based on the possible pollution of underground water and insufficient ground cover material at the site. At yearend, the chairman of the State's House Conservation Committee recommended a feasibility study on returning coal wastes underground and on finding new uses for such wastes. Two abandoned strip pits in Zerbe Township were considered as sanitary landfill sites for 80,000 tons of solid wastes generated annually in Northumberland County. DER approved the cost of a reclamation project at a calm bank near the Boulevard Redevolopment Area in Dickson City, Lackawanna County. The Montgomery County Redevolopment Authority awarded a $46,000 contract to the University Science Center, Philadelphia, to determine if some profitable, or at least useful, use could be found for 1.5 million cubic yards of waste carbonate, magnesia, Engineering and Mining Journal.
