Or. Admin. R. 345-095-0040 - Rules that Apply to Construction

The following rules apply to any ground disturbance activity on the site of a uranium mill:

(1) The certificate holder shall remove native topsoil before excavation for the mine, mill buildings, ponds and tailings disposal sites and shall stockpile the topsoil for later use in site reclamation. The certificate holder shall contour topsoil storage areas to prevent erosion and shall protect the topsoil to retain nutrients needed for subsequent use of the topsoil as a growth medium.
(2) The certificate holder shall not divert or rechannel any perennial streams.
(3) The site certificate holder shall keep the Council informed of drilling or trenching projects conducted to define hydrologic or geologic parameters related to building foundation designs, tailings retention system design, reclamation planning or environmental monitoring. The certificate holder shall notify the Council if site investigations, drillings, trenchings or construction projects including mine development reveal geologic conditions different from those described in the site certificate application. The certificate holder shall provide the information described in this rule to the Department of Energy, the Department of Geology and Mineral Industries and the Department of Water Resources on a timely basis so that the Council and other state agencies may inspect the projects.
(4) The certificate holder shall not use radioactive tailings in the construction of tailings dams.
