Auditing · Verification · Compliance
Compliance,
built to hold.
Stonehenge Trust supports chemical distributors, warehouses, and carriers across ACD Responsible Distribution verification, ISO management systems, and EPA regulatory work — with audit-ready EHS&S documentation engineered to withstand auditor, regulator, and time.
What We Do
Four lines of work,
one standard of care.
Stonehenge Trust is a boutique EHS&S practice serving the chemical distribution and manufacturing sector. We don't chase scope — each engagement is shaped around the regulatory reality of the operator and delivered by the same hands that scoped it.
ACD Responsible Distribution
Third-party verification preparation, RD23 advising and gap analysis for chemical distributors operating under the Alliance for Chemical Distribution's Responsible Distribution Program.
ISO Management Systems
ISO 9001 quality, 14001 environmental, and 45001 occupational health & safety — system design, documentation, internal audit, and stage-1/stage-2 certification support.
EPA Regulatory Compliance
TSCA, RCRA, Clean Air Act, and SPCC programs — permitting, emissions inventories, reporting, audits, and agency response across federal and state regimes.
EHS&S Training & Continuous Improvement
On-site and online training for senior management, operators, and verifiers. Refresher cycles, workshop facilitation, and a continuous-improvement cadence that holds between audits.
Scope of Practice
Who We Serve
Six sectors where our work lives.
We work with operators whose regulatory obligations are continuous, not episodic — and whose compliance posture has to hold across verifiers, agencies, and time.
Chemical Distributors
ACD member distributors preparing for or maintaining Responsible Distribution verification.
Specialty Chemical Manufacturers
Formulators and producers with ISO 9001/14001/45001 obligations and EPA air or wastewater permits.
Warehouses & 3PLs
Bulk-liquid, drum, and IBC operators carrying SPCC, RCRA, and DOT obligations.
Bulk Carriers & Intermodal
Motor carriers and rail-intermodal operators moving hazmat under DOT and ACD verifier scope.
Importers & Tollers
TSCA importer-of-record support, PMN/SNUR strategy, and toll-manufacturing compliance.
Laboratories & R&D
Research operations with EPA, OSHA, and ISO 17025 adjacent obligations.
The Standard
What we hold ourselves to.
We are a small firm. Three principles shape how we take on, scope, and deliver work.
Permanence
Work product is built to be referenced again — by verifiers, auditors, regulators, successors. Documentation that outlasts the engagement.
Fiduciary
Compliance is held in trust. Every deliverable is owed to a standard, not a stakeholder. We carry the obligation.
Restraint
Boutique by design. Small bench, deep work. We take on what we can deliver, and we deliver what we take on.
ACD Verification
Responsible Distribution, verifier-ready.
ACD third-party verification turns on documentation, training, and discipline. We support distributors through the full cycle — gap analysis, remediation, training, and the internal mock verification that makes the real one a formality.
- 01Gap Analysis
Review of current EHS&S documentation against the ACD Responsible Distribution code. Findings package with a remediation plan.
- 02Remediation & Training
Policy and procedure build, recordkeeping, and on-site or online training of senior management and front-line operators.
- 03Verification Readiness
Internal mock verification, evidence package assembly, and walkthrough of the third-party verifier's likely line of inquiry.
- 04Continuous Improvement
Between-cycle cadence — refresher training, regulatory horizon scan, recordkeeping discipline, and verification renewal planning.
