Company. Therefore, CSP's proposal and/or the South Beach alternative may have a
consequential economic effect on the Hasty Water Company and its members. Colorado State
Parks is continuing to work with the Hasty Water County to obtain the necessary grant funding
so there is minimal impact on the Water Company and the community residents.

It is unknown at this time whether or not a new well in the area would have a significant
effect on local ground water level.

The South Beach alternative would be similar to the Colorado State Parks' proposal. The
heightened management of the South Beach area by the Colorado Department of Natural
Resources would have no effect on the demand for potable water since the water supply lines
would probably not be extended to the South Beach area.

Currently, the Corps flood irrigates portions of the Lake Hasty Recreation Area with
water from Lake Hasty. With the CSP proposal, Colorado State Parks plans to irrigate the Lake
Hasty Recreation Area with a new sprinkler system; h.owever, due to the water's high magnesium
content which damages plant foliage, flood irrigation is the only practical means of irrigation in
order to prevent damage to plants and trees.

Construction involved with the development proposed for the Sandstone and Overlook
Recreation Areas as described in CSP's proposal or the South Beach alternative would have
negligible effects on local surface water drainage. Colorado State Parks and their contractors
will comply with all Colorado erosion and sediment control best management practices during
construction and road building/improvement activities. Therefore, none of the alternatives would
have an effect upon surface water resources of the area. The CSP's proposal and the South
Beach alternative's impacts on groundwater are unknown at this time due to lack of availability
of information thereof.

3.1.4 Flood Plains and Wetlands

Executive Order 11988 (Flood Plain Management) provides Federal guidance for
activities within the flood plains of inland and coastal waters. There would be no effect on the
flood plain from any of the alternatives.

Executive Order 11990 (Protection of Wetlands) requires the avoidance, to the extent
possible, of long- and short-term impacts associated with the destruction, modification, or other
disturbance of wetlands habitat. There would be no effect on wetlands from any of the
alternatives.

3.1.5 Hazardous, Toxic, and Radioactive Waste

There are no known hazardous, toxic, or radioactive waste (HTR W) concerns at the John
Martin Project; therefore, none of these alternatives will result in any affect.
