Legislature tightens protections, transparency for proposed quarrying on Chamorro Land Trust Lot 5412

The Guam Legislature on Tuesday amended Bill 7-38 to add mandatory environmental review, local-priority reserves for extracted aggregate, and new transparency and enforcement measures for any license to extract material from Chamorro Land Trust (CLTC) Lot 5412 in the village of Mangilao/Manila.

The package of floor amendments — offered by the senator identified in the record as the gentlewoman from Timuning — requires a full environmental impact statement (EIS) complying with Guam Environmental Protection Agency standards, an independent appraisal of in‑ground aggregate value, at least 50 percent reservation of aggregate for local Chamorro Land Trust homestead and public projects, mandatory "lifeline" pricing for beneficiaries, calibrated weigh scales with automated reporting, and quarterly third‑party audits and public reporting of extraction volumes and royalties.

Why it matters: proponents said the measures aim to protect Guam’s Northern Guam Lens aquifer, cultural sites and homestead beneficiaries while ensuring the CLTC receives a fair return and local housing projects can access construction materials at below‑market rates. Opponents raised concerns that the bill, even as amended, risks environmental damage, would not fully protect families already living on or near Lot 5412, and could still enable large‑scale quarrying that harms sensitive coastal and limestone forest areas.
