A landfill must have an approved Soils and Liner Quality Control Plan (SLQCP) prepared under the
direction of a registered professional engineer. The Department has a professional service agreement with
Parkhill, Smith, & Cooper (PSC) to provide cell design and construction management services. The
Coleman & Assoc. Land Surveying service agreement includes quality control testing and performance data
collections during cell construction, which is reported to the Texas Commission of Environmental Quality
(TCEQ) in the Soil and Liner Evaluation Report (SLER) Geomembrane Liner Evaluation Report (GLER)
and the Flexible Membrane Liner Evaluation Report (FMLER). The SLQCP includes the constructed liner
details, and the soil and liner quality control testing procedures and data.
Coleman & Assoc. Land Surveying will provide on-site surveying and observation during all liner
construction, geomembrane placement required by the TCEQ to meet the SLQCP. The professional services
to be provided, and associated costs of the construction inspection and the specific testing required are
detailed in the proposal received from Coleman & Associates Land Surveying.
