Hydrologic Information |
|
This new document supersedes, with respect to baseline information, a document first made available in 1998 entitled, Managing Hydrologic Information, A Resource for Development of Probable Hydrologic Consequences (PHC) and Cumulative Hydrologic Impact Assessments (CHIA). The 1998 document remains a useful technical reference for preparing and evaluating PHCs and CHIAs even though it has been superseded with respect to hydrologic baseline data. We provide this earlier document as a source of information on hydrologic reclamation plans, PHCs, CHIAs, and the other components of the Surface Mining Law permit application process aimed at assuring the protection of the hydrologic balance.
