Penobscot Bay Conservation Issues

Historic Water Pollution Management. Penobscot Bay has been the receiving waters for sewage waste and industrial waste discharges from bay and river towns since the 19th century. Discharge treatment was primarily dilution until the mid 20th century when the federal government began requiring communities and businesses of all states to meet water pollution control standards.
Beginning with the Federal Water Pollution Control Act of 1948
where states were requested to evolve and enforce their own standards, federal water pollution regulation evolved in 1970 to require that any project requiring a federal permit must be certified to meet state standards, then expanded in 1972 to require projects to meet a host of federal standards. The law is now known as the Clean Water Act of 1972 On June 28, 1966, the State of Maine's Commissioner of Sea and Shore Fisheries, Ronald W. Green, ordered closure of the shellfish beds in the waters of Searsport and Stockton Springs, in upper Penobscot Bay, "due to the polluted condition of the water." The US Department of the Interior's Water Pollution Control Administration and the

then conducted a joint investigation of the lower Penobscot River and upper Penobscot Bay "to determine the sources of this pollution, the direction of travel of this pollution and the degree of economic injury involved." In February 1967, the Water Pollution Control Administration (WPCA) published its findings as
"Report on Pollution - Navigable Waters of the Penobscot River and Upper Penobscot Bay"
The investigation found the sewage from eleven towns, and effluents of thirteen businesses and one university facility were the chief sources of the pollution. According to the report,"substantial economic injury results from the inability to market shellfish or shellfish products in interstate commerce because of pollution caused by sewage and industrial wastes discharged to the Penobscot River and upper Penobscot Bay area and action of state authorities." The WPCA noted that "accordingly the pollution of these navigable waters is subject to abatement under procedures described in Section 10 of the Federal Water Pollution Control Act, as amended" The WPCA report recommended specific water quality requirements for these pollution dischargers, and concluded if the identified pollution sources improved their waste treatment practices, the waters of the upper Penobscot Bay communities of Northport, Searsport,

details some of these early ventures, as these excerpts reveal: "In 1847 Captain Oakes purchased the smack Josephine, with which he began running to Johnson & Young's establishment, at Boston, in 1848, buying a portion of his lobsters in the Penobscot Bay region, where this fishery had just been started. The quantity of lobsters carried by him that year was 40,000.... Lobsters were so abundant at the Muscle Ridges, at this period, that four men could fully supply Captain Oakes with lobsters every trip. In the course of ten days each man would obtain between 1,200 and 1,500 marketable lobsters. In Captain Oakes' opinion, the Muscle Ridges have furnished the most extensive lobster fishery of the Maine coast. He ran to this locality until 1874." "Capt. S. S. Davis, of South Saint George, states that about 1864, when he first began buying lobsters at the Muscle Ridges, three men, tending 40 to 50 pots each, caught all the count lobsters he could carry to market in his smack. He could load 5,000 lobsters at a time, and averaged a trip in 7 to 9 days. This traffic continued for six or seven years. In 1879, Captain Davis bought from 15 men In the same locality, and at times was obliged to buy also of others in order to make up a load." "The fishery at North Haven began in 1848, but did not increase so rapidly at first as in sections farther west, as the smacks would only take the medium-sized lobsters, fearing that the largest would not be able to stand the trip. At Matinicus Island the fishing began in 1868. In 1852 the people on Deer Island began the fishery, and as the smackmen made frequent visits the business rapidly increased. The establishment of a cannery at Oceanville, about 1860, also caused a considerable development of the fishery. The fishery was started at Isle an Haute about 1855, and at Swan Island in the early fifties."
