Proposed expansion of the San Juan Powerplant, San Juan County, New Mexico. Draft environmental statement

Technical Report · Thu Jan 01 04:00:00 EST 1976

OSTI ID:7338310

The proposed three additional units and the existing units would collectively emit a maximum of 2.88 tons of particulates, 106 tons of NO/sub x/ and 34.3 tons of SO/sub 2/ daily. In addition trace metals and radioactive materials in the coal and not trapped in either the bottom ash or the removal systems would be emitted to the atmosphere. These emissions would unavoidably impact the environment. It is conceivable that visibility and human health could be adversely affected in the long-term and there could be injury to surrounding vegetation even though emission standards would be met. Approximately 2,800 acres of land would be disturbed during the life of the Western Coal Company's mining operation. This impact would be temporary and mitigated by revegetation of the mine spoils. Supplemental coal would probably come from another surface mine such as the Navajo Mine nine miles south of the San Juan Powerplant. The impact on vegetation in this area would be similar to the impact at the Western Coal Company Mines. Construction of two proposed transmission lines would utilize existing corridors. One 500kV line would parallel an existing 345kV line and an existing 230kV line would require conversion to 345kV. Construction and operation impact on the land would be minimal in both cases. Eleven alternatives were considered.
