What We Do
Three Divisions. One Team. 40 States.
iSi operates three divisions under one brand — Consulting, Industrial Services, and Facility Support. Whether you need environmental compliance, safety programs, hazmat abatement, or ongoing facility maintenance, you get one team, one point of contact, and national reach.
Consulting Division
Augmentation, not abdication. We plug in to your existing EHS team and close the expertise gaps that create regulatory exposure — environmental, safety, or both — without replacing your people or taking over your programs.
Environmental Compliance
Permitting, reporting, stormwater, air compliance, and regulatory support. We handle the environmental program your team doesn't have time for.
Learn More →Air Permitting
PTE calculations, construction and operating permits, and NESHAP applicability. We keep equipment installs on schedule and permits matched to what you actually run.
Learn More →Safety Consulting
OSHA compliance, safety program development, hazard assessments, and training. When your team needs deeper safety expertise or your environmental lead inherits safety.
Learn More →EHS COOP Program
Your environmental and safety retainer. Foundation, Maintenance, or Partner Program — structured tiers starting at $15,000/year. A national team on call, not a resume on your payroll.
See Pricing Tiers →Industrial Hygiene
Exposure assessments, air monitoring, noise surveys, and IH program development. Same-day response. Fixed pricing. Field-ready team.
Request an Assessment →Phase I Environmental Site Assessments
Phase I ESAs for acquisitions, refinancing, and due diligence. Clear findings, defensible documentation, and lender-ready reports, quoted up front.
Start an Assessment →Audits & Assessments
Targeted audits that find what inspectors look for — before inspectors find it. Safety, environmental, combined EHS, or ISO certification prep.
Safety Audit
Comprehensive OSHA program audits — not just a walkthrough. We evaluate your written programs, training records, and field conditions against current federal and state requirements.
Schedule an Audit →Environmental Audit
Multi-media environmental compliance audits covering air, water, waste, stormwater, permits, and reporting obligations. We map your facility against every applicable requirement.
Schedule an Audit →EHS Audit
The integrated audit — environmental, health, and safety in one assessment. One site visit, one report, full regulatory picture. More efficient than separate audits and less likely to miss cross-program gaps.
Schedule an Audit →ISO Audit
Internal audits, gap analyses, and certification prep for ISO 14001 and ISO 45001. We support your full audit cycle — from internal reviews to registrar surveillance prep.

Most clients start with one service and discover they need another. That's the advantage of one team covering environmental, safety, and industrial — you never have to source a second vendor.
