Randell Obrary Cove Special Service District 1105 S Sevier HWY Joseph, UT 84739-1175
Subject: Notice of Removed Asbestos Monitoring for Cove Special Service District; UTAH21046 Randell Obrary:

This letter serves as notification that asbestos monitoring is no longer required at the Cove Well #1 (identified as WS001). After reviewing geological studies and mining records of the Henry Mining District, Source
Protection staff believe the risk of natural asbestos deposits within the collection area of the Cove
Well # 1 (WS001) to be negligible. This determination is based on the following:
• Historical mining records for the Henry Mining District in Sevier County indicate that extracted minerals include diatomite, iron, magnesium, silver, and uranium. There is no
confirmation that asbestos-hosting rocks, such as serpentine or tremolite, were ever found
or mined in the district.
• The Trinity Prospect is the only location in the district where serpentine has been mentioned, appearing in a single study (Kenneth C. Bullock’s 1981 Minerals and Mineral
Localities of Utah). However, the report provides no details on the prospect’s exact
location or any evidence that it progressed into an active mine. While the presence of magnesium, iron, and intrusive bodies suggests that serpentine was a possibility, this was never confirmed, and the claim remained a prospect.

• Local geology (Hintze and Others, 2008) indicates that the Antelope Range is composed primarily of felsic to intermediate rocks such as rhyolite, monzonite, and granodiorite—none of which are typically associated with serpentine. Serpentinization is generally linked to ultramafic rocks, which are absent in the geologic mapping of the Antelope Range.

• Asbestos mining in Utah has been historically limited. The only dedicated asbestos mine was the Tremolite No. 1 Mine, located in the Antelope Springs Mining District of Millard County.

• Nearby historical mining operations focused on uranium and diatomite production, with no indications of asbestos-bearing rock. Additionally, drill logs from the area show no evidence of asbestos-containing formations.
Based on these findings, an asbestos monitoring waiver has been issued an no further asbestos
testing is required. An updated monitoring schedule can be viewed any time at waterlink.utah.gov under the water monitoring section. Thank you for your efforts in maintaining a clean drinking water system. Please contact David
Kruse at (385)-566-7789 or [e-mail] for questions regarding the source monitoring and
reporting requirements for your water system or Noah Zorsky at [phone] or [e-mail] for source protection assistance. Sincerely,
