I have reviewed the proposed revisions to the New Horizon Mine permit to allow for either grazing or
haying in the irrigated pasture reference area. My questions are listed below.
1. Plans for livestock grazing and haying. An introductory sentence would be helpful to explain
that the irrigated pasture reference area will be either grazed or hayed to simulate the
management on the reclaimed irrigated pasture land.
2. Please add to the end of the Plans for livestock grazing and haying discussion that winter grazing
by cows, deer and elk is common practice and may occur on all areas with supplemental hay
provided when . (Please explain when the supplemental hay is provided.) Domestic
grazing animals will be removed prior to irrigation and spring germination of planted species.
Generally, animals will be removed no later than March 30 of each year.
3. One other question I have on the PR6 approved version focuses on the expected rate of water.
The narrative says, "Water will be applied to the reference area based on the ration used for the
irrigation of Reclaimed Irrigated Pastureland on the Lloyd Property ". The Lloyd property has not
been reclaimed yet and it is not representative of the lands that have been reclaimed east of
2700 Road and that will be considered for bond release prior to the Lloyd property. Please
revise this statement to indicate what the expected rate of water will be for ALL lands including
those to the east of 2700 Road, the Lloyd property, and the Benson west property. In TR58, the
Division approved, "10 shares of water to irrigate the reference area of 6.81 acres. The
reclaimed area will receive approximately 1 share per acre if a side roll is used. If flood irrigation
is used, the same application rate as the reference area is used, which is 1.64 shares per acre."
Please revise the discussion on the expected rate of water so that it applies to all reclaimed
lands.
