About this file
This is a Site Assessment Form for onsite wastewater system feasibility prepared by TriCounty Health Department for Uintah and Duchesne Counties in Utah. The assessment evaluates the parcel located at 19001 Wildlife Refuge Road, Randlett, UT 84063 (SEC 11, T8S, R20E), owned by the Ouray National Wildlife Refuge, for construction of an onsite wastewater system to serve a Commercial Visitor Center and staff housing.
The site has been determined feasible for wastewater system construction, with Absorption Trench and Deep Wall Trench identified as suitable system types. The soil exploration revealed loam soil composition with no bedrock present at a depth of 120 inches. Test site conditions include a 1% southward slope with no downslope exceeding 35% within 200 feet, no open water within 200 feet, and no elevation requirements. Maximum groundwater level is located at 120 inches depth. System requirements specify a hydraulic loading rate of 0.5 and a maximum drainfield depth of 72 inches from grade. The proposed drinking water source is Ouray Park WID. The assessment was certified by LEHS David Koons on August 28, 2026, and expires two years from that date. The form explicitly states this assessment is not a permit to construct an onsite wastewater system and that any design must include conditions marked as "Yes" in the assessment.
