Quality Assurance

DEEP's quality assurance policy maintains that all environmental data collected, generated and processed is scientifically valid; of known precision and accuracy; sufficiently complete and representative for the intended purpose; comparable to data collections and analyses similar in scope and purpose; and legally defensible, as may be necessary for the intended purpose. The data and information used as a basis for environmental program decisions, i.e., establishing environmental quality standards, emissions limitations, permit limits and resource management plans, shall be in a form that may be clearly and understandably presented to the public. (From DEEP’s Quality Assurance Policy)

Quality Management Plan (QMP)

DEEP’s Quality Management Plan is required by EPA for any organization that accepts funding and collects environmental data.  This document defines quality related procedures, roles, responsibilities and authorities.  The QMP documents DEEP’s Quality System, which is a set of policies, processes, and standard procedures that DEEP uses to ensure the success of its work.  QMPs are revised every five years.  DEEP’s Quality Management Plan was updated in 2020 and is in effect until December 2025.

Quality Assurance Project Plans

A Quality Assurance Project Plan outlines the technical activities and procedures that will be taken to ensure the data collected and analyzed meets project requirements.  EPA funded projects must have an approved QAPP before sampling begins. Within DEEP, management and staff in the Bureaus of Air Management, Materials Management and Compliance Assurance, and Water Protection and Land Reuse have the primary responsibility and authority for ensuring that projects requiring QAPPs within their bureau have been developed and approved by EPA.
