Overview

Brownfields are properties where redevelopment is complicated by actual or suspected contamination. In Pomona, environmental review for development applications incorporates hazardous-materials screening and may trigger site assessment, cleanup plans, or referral to state agencies. For local planning review and environmental checklists use the Planning Division guidance.Planning Division[1]

Site Testing & Assessment Steps

  • Phase I Environmental Site Assessment (ESA) to identify recognized environmental conditions.
  • If Phase I indicates risk, perform Phase II sampling and laboratory analysis for soil, groundwater, and vapor intrusion.
  • Submit assessment reports with permit or entitlement applications so reviewers can determine mitigation needs.
  • Prepare a Remedial Action Plan (RAP) or equivalent if contamination requires active cleanup or controls on reuse.

When state programs apply

Pomona may coordinate with the California Department of Toxic Substances Control (DTSC) or regional water boards for complex site cleanups; developers should review state brownfields and site cleanup programs for funding or oversight options.DTSC Brownfields[3]

Submit assessments with permit applications to speed review.

Penalties & Enforcement

Enforcement for failure to investigate or remediate contamination in Pomona is handled through the city departments for planning, building, and code enforcement, and may involve state agencies for hazardous releases. Specific monetary penalties or fee schedules for brownfield cleanup are not always itemized on the city pages and may be set by referenced state programs or by administrative orders.

  • Monetary fines: not specified on the cited page; amounts depend on the enforcing instrument or state agency orders.
  • Escalation: first, repeat, and continuing offence treatment is not specified on the cited page.
  • Non-monetary sanctions: cleanup or remediation orders, stop-work orders, liens, or referral to state agencies and civil actions are possible.
  • Enforcer and inspection: City of Pomona Planning and Code Enforcement carry out local inspections and referrals; complaints may be submitted through the city Code Enforcement contact page.Code Enforcement[2]
  • Appeals and review: appeal routes depend on the permit or enforcement instrument; time limits for appeals are not specified on the cited city pages and may be set in the municipal code or permit conditions.
Failing to report contamination can trigger costly cleanup orders.
