**Project Type 1.** [Dirt ditches]{.underline} **converted** [to lined
ditches, pipelines or gated pipe.]{.underline}

(High Priority). Includes any combination of off-farm and on-farm
delivery and tail

water ditches, **treating 75% or more** of the offered irrigated acres

> for the tract being contracted or cost of salt savings are below \$80
> per ton.

**Project Type 2.** [Dirt ditches]{.underline} **converted** [to lined
ditches, pipelines or gated pipe]{.underline}.

(Medium Priority) Includes any combination of off-farm and on-farm
deliver and tail

water ditches, and subsurface drains **treating less than 75%** of the

irrigated acres of the tract being contracted; and/or

**conversion** [of irrigation systems resulting in over 15% increase

[efficiency.]{.underline} **(See chart below)**. (Or in Montrose County
subsurface

drain only plans, or land leveling only plans). (In Mesa County sub-

surface drains will be limited to subsurface interceptor drains.) or
cost of salt savings is between \$80 and \$100 per ton.

**Project Type 3.** [Conversion]{.underline} of irrigation systems
**resulting in less than 15%**

(Low Priority). **increase in efficiency**. (See chart below). Or other

projects where cost of salt saving exceeds \$100 per ton.
