Area-Specific Findings Sample Clauses

Area-Specific Findings. Line 1 1. The types of materials processed at Line 1 and potentially discharged as waste included: Composition B, PBX, RDX, TNT, baratol, and boracitol. 2. Line 1 began operations in 1941 and continues to operate. An abandoned containment impoundment (Former Line 1 Impoundment) was located near Line 1. The Impoundment was created in 1948, when a dam was constructed along the upper reaches of Brush Creek to impound wastewater effluent discharged from Line 1. 3. In the 1950’s, Line 1 was expanded to include 2 separate production lines, which doubled the plant capacity for producing the high explosive components for weapons. This expansion consisted of the addition of four new process buildings: an x-ray/final machining facility (1-100), a rest house (1-07), a machining bay (1-40) and an assembly bay (1-61). Additionally, six bays in 1-10 and 1-12 were converted into machining bays. A laboratory (1-60) was also constructed after 1-08-2 was demolished. Storage of radiological materials occurred at Buildings 1-11, 1-13 and portions of 1-40 and 1-61. 4. The Former Line 1 Impoundment extended about 1300 feet upstream of the dam and covered approximately 3.6 acres. During periods of high flow, the Impoundment may have reached as far as 2400 feet upstream and covered approximately 7.5 acres. 5. The primary function of the Former Line 1 Impoundment was to allow settlement of particulates from explosives-contaminated wastewater prior to discharge downstream. 6. Wastes discharged into the Former Line 1 Impoundment included TNT and its degradation products. 7. No known water treatment process was employed at the Former Line 1 Impoundment other than the intermittent addition of fly ash to adsorb explosive components and reduce color. 8. The Former Line 1 Impoundment was addressed in an Army removal action. Approximately 8300 cubic yards of explosive-contaminated sediments were excavated from the Line 1 Impoundment and disposed at the Inert Disposal Area in this removal action. 9. The Line 1 production facility is approximately 1700 feet by 4900 feet, encompassing an area of approximately 194 acres, situated on the northeast portion of the IAAAP. The facility was constructed in 1941 and was in operation from late 1941 to September 1945. From 1948 to 1975, Line 1 was operated by the AEC. During this period, boratol and boracitol were used. Line 1 is currently a missile warhead, cartridge and grenade LAP facility. The principal feedstocks are TNT, Composition B, PBX, and R...
