Petroleum Service & Calibration

What Petroleum Service & Calibration does

Petroleum Service & Calibration, Inc. (PS&C) is a privately held, founder-owned compliance testing services company headquartered in Denver, North Carolina. Founded in May 2000 by Jeffrey D. McCrary and Jean Jenkins-McCrary, PS&C has built a 20+ year regional practice focused on federal and state regulatory compliance testing for underground storage tank (UST) systems, plus fuel dispenser meter calibration. The company operates across seven southeastern and Midwestern states (NC, SC, VA, TN, GA, KY, IN) using certified field technicians and a fleet of specialized testing equipment (Estabrooks EZY CHEK testers, Mark Model helium detectors, 50/60/100-gallon provers) to perform tank, line, leak detector, spill bucket, sensor, shear valve, overfill prevention, interstitial, containment integrity, and cathodic protection testing, as well as high-flow and standard meter calibration, Stage I vapor recovery, monthly walkthrough inspections, pre-inspections, and state inspection coordination. PS&C reports having serviced 2,000+ customer locations, with named enterprise accounts including Sheetz, Circle K, Duke Energy, and the City of Charlotte alongside a long tail of regional petroleum distributors and fuel retailers.

The company's product architecture is anchored by UST-Comp, a proprietary compliance testing and management application established May 18, 2012. UST-Comp is a custom in-house system maintained by a Senior Application Developer; it centralizes testing schedules, federal and state regulatory deadlines, test results and failure records, retest reminders, emergency testing oversight, and a budgeting feature, delivering 24/7 online portal access to customers. The broader product surface includes a one-stop compliance practice supplemented by a curated nine-partner referral network covering SIR (TotalSIR), cathodic protection (Protective Technologies), site assessments (Thompson Geologic, ATC Group Services), and regional petroleum equipment service work (HCN Petroleum Equipment, A-1 Petroleum Services, Petroleum Equipment and Service, Law Petroleum, Southern Petroleum Services).

PS&C's business model is a mix of one-time and recurring professional services with a layer of subscription-like recurring revenue. Revenue streams include compliance testing engagements (typically annual or triennial), recurring monthly walkthrough inspection contracts in seven states, Class AB operator inspection subscriptions, meter calibration work, and emergency reactive testing during Notices of Violation (NOVs). Services are quote-based, ordered via phone (704-489-1671) or website request forms, delivered on-site by dispatched technicians, and billed per scope. The company is privately held with no disclosed external funding, no parent company, no M&A activity, and a leadership bench extending from the founders to General Manager Zachary S. Elliott (joined 2008) supported by a senior developer, office management, and scheduling staff. Marketing is referral- and testimonial-driven, anchored by an extensive catalog of public customer quotes on the corporate website (testmytanks.com).
