Quality Assurance

Grace Consulting, Inc. has considered quality assurance/quality control as one of our top priorities since the inception of the firm. In addition to the concepts described regarding TOTAL QUALITY, GCI has complete QA/QC packages for all of our field sampling for air emissions work, and also requires QA/QC of all engineering and science activities.

Tyson Stiles, QSTI and Quality Manager for GCI, in conjunction with the Senior Staff, have worked tirelessly to implement a comprehensive Quality Assurance Program, which applies for initial preparatory activities through report generation. This includes the following measures:

  • Technical staff follows standard operation procedures under the direct supervision of a senior staff member.
  • Any field measurements taken are directly recorded on field data forms and input into an on-site computer.
  • Proper chain-of-custody is followed for all samples collected in the field for analysis at the analytical laboratory.
  • All data records are filed and archived.
  • Data submittals and reports are validated, reviewed, and approved by management prior to release.

GCI operates in compliance with the ASTM D 7036-04 Standard Practice for Competence of Air Emissions Testing Bodies and is organized so that our facilities and resources meet the requirements of ASTM D-7036. GCI has also received Interim Accreditation regarding our Quality practices.
