If the unanticipated discovery involves human remains and/or associated objects on USFS lands, all work must immediately cease within one hundred (100) feet of the discovery and the USFS must be notified immediately of the discovery. The area of the find must be clearly

7 | P a g e delineated, protected, and secured until USFS staff have been contacted and have had an opportunity to evaluate the nature and significance of the discovery. All discoveries on USFS lands will be treated in accordance with the Native American Graves Protection and Repatriation Act (PL 101-601; 25 United States Code 3001–3013), and work must not resume in this area without authorization from the USFS.

1.11 PROTECTION OF NATURAL RESOURCES

Confine all operations to work limits of the project. Prevent damage to natural surroundings.

d. ALTERNATIVE ABANDONMENT METHODS

16 | P a g e

i. Use ADWR-approved alternative abandonment methods when it is determined that the disturbance of the casing and/or gravel packed zones would negatively influence the sealing of the well.

v. ADWR Alternative #4: Wells that penetrate a single aquifer without vertical flow components, and no water quality contamination issues exists.

1. Fill well with one or more of the following mixtures:

a. Cement grout (including neat cement grout, cement-bentonite grout, and sand-cement grout).

b. Concrete or Concrete grout.

c. Sand-bentonite grout.
