Planning commission approves Robinson Loop material‑site permit after restrictions on hours, noise and berms

The Kenai Peninsula Borough Planning Commission voted Dec. 8 to grant a conditional land‑use permit to reopen the Robinson Loop material site for DOT’s Sterling Highway Safety Corridor improvements, but only after adding limits and safeguards demanded by residents.

The permit, adopted as Planning Commission Resolution 2025‑33, was amended on the floor to require that “material extraction activities including equipment operation may only occur between the hours of 6 a.m. and 9 p.m. Alaska standard time,” that all on‑site equipment use multi‑frequency white‑noise backup alarms, and that earthen berms specified in the resolution be increased from 6 feet to 10 feet. Commissioners also added a condition requiring a public hearing if the permit is renewed at five years instead of processed administratively.

The applicant, QAP, represented by project manager Spencer Newins, said the site would supply gravel for the Sterling Highway project, and that the company expects to extract enough usable material for “probably 2 seasons worth of work” rather than a long‑term operation. Newins told the commission the company will not process material (no crushing or asphalt production) on the Robinson Loop parcel and “we will not be mining below into or below the water table.” He added that the firm committed to dust control using water trucks and, where necessary, chemical suppressants, and said the firm could install 10‑foot berms and use white‑noise alarms.

Residents offered prolonged and sometimes emotional opposition at a packed hearing. Don Douthat, who said he has lived next to the pit for 40 years, described prior operations that “made my house shake on a regular basis” and raised concerns about property values, wells and reclamation. Several other neighbors urged the commission to deny nighttime work, point to an active pit a half‑mile away that they said could supply the state project, and demand stronger bonding and monitoring for wells and reclamation.

Technical testimony from McLean Consulting’s engineer, identified as Gina, said the applicant installed 16 test pits, found groundwater only in one northeastern hole and will install observation/monitoring wells to track groundwater location. Gina noted noise attenuates quickly with distance and that properly sited berms can reduce decibel levels.

Commissioners weighed the borough’s new material‑site code, which expanded review of prior‑existing use pits. Several members said the ordinance gives them authority to require site‑specific mitigation and to withhold exceptions for after‑hours work when residential density is high. Commissioner Epperheimer said he found the request for nighttime hauling insufficiently justified; others pushed to preserve construction scheduling flexibility if DOT requires night hauling but only with concrete evidence.

The commission’s final package of conditions narrows hours of operation, mandates white‑noise back‑up alarms, increases berm heights and requires a five‑year renewed permit to return to the commission for a public hearing. With those changes the commission voted to approve the CLUP.

What happens next: the permit as adopted contains specific mitigation and monitoring conditions; enforcement and inspection responsibilities were discussed during the hearing and will be administered by borough staff. The project still depends on DOT design and federal funding before large‑scale work begins.
