Environmental Protection California 4 Minutes Read ยท published February 09, 2026 Flag of California

Bakersfield, California property owners and developers encountering suspected brownfields must navigate local, county, and state processes to assess contamination and pursue cleanup. This guide explains the typical steps to evaluate a site, who enforces testing and remedial work, what permits or programs may apply, and how to file complaints or request inspections. It is intended for property owners, prospective purchasers, developers, and community groups seeking clear, actionable next steps in Bakersfield.

Overview of Brownfield Testing & Cleanup

Brownfields are properties where past uses may have left hazardous substances or petroleum contamination that complicate reuse. Initial steps usually include a records review, Phase I Environmental Site Assessment, followed by sampling (Phase II) if indicators of contamination are found. Oversight and technical standards for sampling and remediation in Bakersfield are commonly provided by state and regional agencies rather than a specific city brownfields ordinance.

Begin with a Phase I assessment to limit unexpected liabilities.

Who Oversees Testing and Cleanup

Primary oversight for site assessment and cleanup in the Bakersfield area can involve the California Department of Toxic Substances Control (DTSC) for hazardous waste sites and cleanup programs[1], and the Central Valley Regional Water Quality Control Board for impacts to groundwater and surface water[2]. Local public health and environmental health divisions (Kern County) may handle complaints, initial investigations, and referrals to state agencies[3].

Penalties & Enforcement

Enforcement for contamination and cleanup in Bakersfield is typically carried out by state and regional agencies, with local agencies assisting in complaint intake and site referrals. Specific monetary fines and schedules are not consistently listed on the primary program pages for site cleanup; where amounts or daily rates are set they appear under statute or case-specific orders rather than a single municipal table, and therefore are not specified on the cited page[1].

  • Monetary fines: not specified on the cited page; state orders and federal statutes may authorize civil penalties depending on the program[1].
  • Escalation: first vs repeat/continuing offences handled by administrative orders, consent decrees or referrals to court; specific ranges not specified on the cited pages[2].
  • Non-monetary sanctions: cleanup orders, remediation schedules, site access requirements, site controls (institutional/engineering controls), and referral to civil enforcement or injunctive relief are common remedies and authorities are set out on state/regional pages[1].
  • Enforcer and complaint pathway: DTSC and the Central Valley Water Board oversee cleanup programs and may issue orders; Kern County Environmental Health accepts local complaints and coordinates initial response[3].
If you suspect contamination, report it promptly to the county environmental health office to document the issue.

Appeals, Reviews, and Time Limits

Appeals or protest procedures vary by enforcing agency. Where the DTSC or a Regional Water Board issues an enforcement order, the order documents appeal rights and deadlines; exact time limits and procedures are program-specific and are not specified on the cited page[1]. For county actions, contact Kern County Environmental Health for local administrative review steps[3].

Common Violations and Typical Remedies

  • Failure to report known releases: may lead to orders to investigate and remediate; monetary penalties not specified on cited pages[1].
  • Unpermitted soil/groundwater disturbance: stop-work orders and corrective actions; fees or fines are case-specific.
  • Improper handling or disposal of hazardous materials: enforcement by state hazardous waste authorities and possible cleanup orders.

Applications & Forms

There is no single Bakersfield municipal brownfield cleanup form published on a city page. State and regional programs provide enrollment materials, voluntary cleanup program forms, and guidance; specific form names and fees depend on the chosen program and are listed on the program pages cited below[1]. Kern County Environmental Health provides complaint intake and guidance for local reporting[3].

How-To

  1. Confirm site history: gather title records, past uses, permits and known spills.
  2. Order a Phase I Environmental Site Assessment to identify potential Recognized Environmental Conditions.
  3. If indicated, complete Phase II sampling and analysis under an EPA- or state-accepted protocol.
  4. Submit findings to the appropriate agency or enter a voluntary cleanup program based on agency guidance and site risk.
  5. Implement a remedial action plan approved by the enforcing agency and document closure or no-further-action status.

Action Steps for Property Owners and Developers

  • Order a Phase I ESA from a qualified environmental consultant immediately.
  • Contact Kern County Environmental Health to report suspected contamination and request guidance[3].
  • Coordinate sampling plans with the enforcing agency if contamination is confirmed[1].
  • Budget for assessment and remediation; seek federal or state brownfields grants if eligible.
Document each step and keep records of notifications, samples, and reports.
