Regulatory Compliance

Receiving an enforcement notice or notice of violation from a regulatory agency is challenging. Riparia helps clients understand their regulatory situation clearly, evaluate their options honestly, and take the right corrective actions to resolve violations and restore stormwater compliance and water quality standards.

Delivering Compliance Through Expertise & Relationships

Our management team has extensive experience handling Notice of Violations (NOVs), NPDES permits, Ms4 permits, and walking clients through the enforcement response process. Our crews are experienced in executing the maintenance and inspection work needed to bring facilities back into compliance. We also have longstanding relationships and good working rapport with the regulators and inspectors who administer these programs, an advantage for our clients who are looking to resolve issues and move forward.

Who This Is For

  • Industrial stormwater permit holders who need to comply with NPDES and Ms4 requirements—including required sampling, documentation, and reporting—and are struggling to keep up with the administrative and field demands of ongoing compliance.

  • Business owners who have received a notice that their facility is out of compliance and need the situation resolved promptly by someone who understands both the regulatory process and the field work required to address it.

  • HOAs that have received a compliance notice regarding and need a knowledgeable partner to assess the situation, communicate with the regulator, and execute the corrective actions required.

  • Private landowners who have received a wetland violation notice and are unclear about their present situation, what options are available, and what steps are required to resolve the matter.

What To Expect

Riparia’s compliance and violations service is built around honest assessment, clear communication, and effective execution. You can expect a straightforward, experienced assessment of where you stand, what your options are, what each of those options realistically costs, and all associated risks. Riparia’s engagement typically includes:

  • Thorough review of all enforcement documentation, prior actions, maintenance agreements, plan sets, and site records to establish a clear picture of the situation
  • An honest, direct assessment of the regulatory framework you’re subject to, your compliance options, and the real costs, risks, and benefits of each
  • Advocacy on your behalf—once you’ve made an informed decision about how to proceed, we stand behind that decision and work to advance your interests
  • Active communication with regulatory authorities, maintained along whatever communication pathway you direct and with full transparency throughout
  • Formal appeal support if that is the path you choose, including preparation of written appeal materials and navigation of the administrative process—with the understanding that if legal representation becomes necessary, we will support that process but cannot serve in a legal role
  • Execution of the agreed corrective action plan, with adaptive modifications as field conditions and regulatory feedback warrant

How We Work

  • 1. Document Review

    We collect and review all relevant documentation—enforcement notices, prior correspondence, maintenance agreements, as-builts, and records of previous corrective actions—to build a complete picture of your situation.

  • 2. Understand Your Position

    We take time to understand your goals, constraints, and priorities so the compliance path we recommend reflects your actual situation.

  • 3. Options Assessment

    We develop a clear set of compliance options, identify the realistic costs and risks of each, and provide our professional recommendation. You make the decision, we make sure you have the information you need.

  • 4. Establish Compliance Timeline

    We work with the regulatory agency to establish an agreed-upon compliance schedule and create a documented framework that protects you while corrective work proceeds.

  • 5. Formalize the Corrective Action Plan

    We prepare a contract-level corrective action plan with the agreed timeline, clearly stating assumptions and exclusions based on current knowledge and pending due diligence.

  • 6. Investigation & Execution

    We conduct required field investigations to validate the plan, execute the corrective actions, and adapt our approach as investigations and regulatory feedback evolve.

Why Stormwater Compliance Matters

Regulatory enforcement actions don’t resolve themselves. Whether you’ve received a formal notice of violation, a compliance order, or enforcement communication from a regulatory officer, the clock starts running from the moment you receive it—we help you respond thoughtfully and promptly.

Reducing Financial Liability

Failing to respond to an enforcement action puts you at significant risk of escalating monetary penalties. In many jurisdictions, unpaid penalties can ultimately be placed as a lien against the property. Beyond regulatory fines, if a facility that received an enforcement notice subsequently fails and causes damage to a downstream property, an owner who declined to take action can face civil liability for those damages.

Reducing Legal Liability

The consequences of ignoring enforcement actions can extend well beyond financial penalties. Regulatory authorities have the power to revoke business licenses, suspend connections to public utilities, and in serious cases, pursue criminal prosecution. Responding promptly and in good faith—with a well developed compliance plan—is the most effective way to protect against these outcomes.

HOA Stormwater Facility — Compliance & Rehabilitation

An HOA engaged Riparia after experiencing repeated stormwater facility failures, inconsistent enforcement guidance, and ineffective repairs from previous contractors that addressed symptoms rather than underlying issues. Riparia conducted a comprehensive review of project documentation, performed site evaluations, identified the root causes of failure, and developed a clear assessment of feasible solutions, including realistic timelines and lifecycle cost considerations.

When regulatory requirements later shifted in ways that conflicted with prior written agreements, Riparia advocated on the client’s behalf by presenting the documented history, successfully eliminating the proposed compliance deadline, and securing permit credits to help offset additional project costs. The result was a compliant, long-term rehabilitation solution delivered within the regulatory framework and designed for lasting performance.
