Environmental Compliance Audit
Environmental Compliance Audit Services
A single inspection covers one permit or media. A comprehensive environmental compliance audit covers your entire program — air, water, waste, stormwater, RCRA classification, Tier II reporting, and record-keeping. iSi audits against EPA, state, and local requirements simultaneously. Identify gaps before an inspector walks in.
What an Environmental Compliance Audit Covers
Comprehensive assessment across all environmental media, regulatory frameworks, and compliance obligations. Every finding includes the regulatory citation, potential consequence, and remediation deadline.
Air Emissions & Permits
Permitted emission sources, potential-to-emit calculations, monitoring requirements, permit compliance, NESHAP applicability, MACT standards, operational limits tracking, and continuous emissions monitoring (CEM) verification.
Wastewater & Water Discharge
NPDES permit compliance, wastewater discharge monitoring, outfall characterization, pretreatment program participation, industrial wastewater treatment system performance, and reporting accuracy.
Stormwater Compliance
SWPPP (Stormwater Pollution Prevention Plan) review against current site conditions, benchmark monitoring verification, visual inspection documentation, NOI/NOT status, and corrective action tracking.
Hazardous Waste & RCRA
Generator classification (LQG/SQG/VSQG), cradle-to-grave documentation, hazardous waste characterization, manifest completion, storage time limits, container management, and accumulation area compliance. Verify generator status aligns with actual waste volumes and streams.
Chemical Inventory & Tier II Reporting
EPCRA Tier II accuracy verification through physical inventory reconciliation, chemical storage location mapping, hazard classification alignment, TRI reporting confirmation, SARA 313 applicability, and annual emissions statement verification.
Environmental Management & EPA Self-Audit
Review of environmental aspects assessment, permit tracking and documentation, compliance calendar execution, regulatory deadline tracking, staff training and competency, and EPA self-audit policy eligibility determination (disclosure protection).
Compliance Gaps Most Facilities Miss
These scenarios appear compliant on paper. Underneath, they carry significant regulatory exposure. We see them at nearly every facility we assess for the first time.
Unpermitted Emissions Source Created During Operational Change
Your facility added equipment, modified a process, or relocated operations. Air emissions changed. But did the change trigger air permit modification requirements? Many manufacturers modify operations without realizing the change creates a new permitted emission source — or modifies an existing permit condition.
Operating without a current permit, or violating permit limits after a modification, is an EPA violation. The facility is liable — not the operations team that made the change.
EPA air permit violation: $93,058 per day of violation. A month of non-compliance exceeds $2.7 million.

Waste Stream Miscategorized — Generator Status Is Wrong
Your facility self-identifies as a Small Quantity Generator (SQG) or Conditionally Exempt Small Quantity Generator (CESQG) based on historical waste volumes. But production has increased, and you're now generating quantities that push you into Large Quantity Generator (LQG) status. You're managing the waste as an SQG, but the EPA and state classify you as an LQG.
The violation exists regardless of intent. Operating under the wrong generator classification triggers RCRA civil penalties, increased EPA inspection frequency, and state enforcement pressure.
RCRA generator misclassification: up to $93,058 per day of violation. Storage, handling, and manifest requirements differ by classification.

Tier II Filed — But Chemical Inventory Doesn't Match What You Reported
EPCRA Tier II reporting happens on schedule. The form is signed and filed. But when was the last time you physically walked the facility and verified the chemical inventory matches what you reported to the state?
Most facilities update Tier II based on assumptions about what's in storage — not by counting and weighing what's actually on-site. Significant discrepancies between what you reported and what you have become EPCRA violations.
EPCRA reporting violations: $25,000–$75,000. Repeated violations trigger state enforcement, increased inspection frequency, and potential criminal referral.

Compliance Gaps Cost Exponentially More Than Prevention
EPA penalties can reach $93,058 per day of violation. A comprehensive environmental compliance audit that identifies the gap before enforcement costs a fraction of a single penalty day. After enforcement, expect $25,000–$75,000 in response costs plus increased inspection frequency for 3–5 years. Prevention is far cheaper than remediation.
We Plug In. You Level Up.
Most of the environmental compliance burden isn't the hard decisions — it's the 60% of surrounding work: tracking, reporting, documenting, monitoring, permit management, regulatory deadlines, and proof of compliance.
iSi plugs into your team to handle that 60% so your internal EHS leader focuses on the judgment calls that actually require their on-site presence and operational knowledge. An environmental compliance audit documents the entire program — what you have, what you're doing, where you meet requirements, and where you don't. It makes your compliance person-independent. Any qualified team member can execute from the audit findings.
After the audit, iSi can support the corrections, train your team on new processes, or hand off to you with a clear roadmap. You decide how much partnership you need — one audit, or ongoing support through an EHS COOP retainer.
What You Get: The Environmental Compliance Audit Report
Every environmental compliance audit project delivers a complete report — not a checklist. The report includes:
- Complete findings across all environmental media (air, water, waste, stormwater)
- Regulatory citations for every finding (EPA code, state rule, local ordinance)
- Potential consequence of each gap (penalty magnitude, enforcement trigger)
- Priority ranking by compliance deadline and regulatory severity
- Estimated remediation cost and timeline for each item
- Corrective action plan with responsible party and due date
- Facility-specific regulatory roadmap for the next 12 months
Reports are written for facility managers and operations leaders — clear findings, prioritized recommendations, and compliance context. No padding. No filler. Your team reads it once and knows exactly what to do and why it matters.

The Single-Person Environmental Knowledge Problem
If all your environmental compliance knowledge lives in one person's head — and that person gets sick, leaves the company, is promoted, or is unavailable during an inspection — what happens to your permits? What happens when the EPA calls?
Your permits don't pause. Your reporting deadlines don't move. Your compliance obligations continue. If an EPA inspector or state regulator walks in and that person isn't there to explain your program, your liability doesn't disappear — it becomes company-wide and personally liable.
An environmental compliance audit documents your entire program — what you have, what you're doing, where you meet requirements, and where you don't. It makes your compliance person-independent. Any qualified person can execute from the audit findings. Protects your people. Protects your company. Makes you scalable and insurable.
Environmental Compliance Audit Questions
What does an environmental compliance audit cover?
A comprehensive environmental compliance audit covers all environmental media: air emissions, wastewater discharge, stormwater management, solid and hazardous waste classification, chemical inventory, Tier II and EPCRA reporting, permit conditions and compliance, RCRA waste management, and regulatory record-keeping. iSi audits against federal EPA requirements, state-specific regulations, and local ordinances simultaneously.
How much does an environmental compliance audit cost?
Starting at $2,500 depending on facility complexity, number of permits, and scope of environmental media covered. EPA civil penalties for non-compliance can reach $93,058 per day of violation per regulatory area (RCRA, air, water, stormwater). An environmental audit identifying gaps before enforcement costs a fraction of a single penalty day.
How is this different from an EPA inspection?
An EPA or state agency inspection is triggered by a complaint, scheduled compliance check, or allegation — it covers a narrow scope, often a single permit or media. An environmental compliance audit is proactive, comprehensive, and covers your entire environmental program — all permits, all media, all reporting requirements, all compliance obligations.
How often should we conduct environmental compliance audits?
At minimum annually. More frequently if your facility has undergone operational changes, acquired new permits, modified waste streams, or has prior enforcement history. iSi COOP retainer clients receive quarterly environmental compliance oversight and proactive updates as part of their annual program.
What is EPA self-audit policy?
The EPA Audit Policy provides enforcement discretion and penalty reductions if a facility voluntarily discovers and discloses environmental violations through an internal audit, takes prompt corrective action, and meets other conditions. Eligibility requires no federal enforcement action in the past five years and no prior knowledge of the violation. iSi audits identify whether your facility qualifies and can position an audit to maximize EPA self-audit policy protection.
What happens after the audit is complete?
iSi delivers a comprehensive report organized by compliance priority, regulatory citation, potential consequence, and remediation timeline. Findings are ranked by severity and regulatory deadline. The report includes a corrective action plan with estimated costs and compliance dates. Your team uses the report to allocate resources and execute corrections. iSi can support implementation or hand off to your internal team.
