FIGURE A4.1
PROJECT ORGANIZATION CHART
In 1991, the Texas Legislature passed the Texas Clean River Act (Senate
Bill 818) in response to growing concerns that water resource issues were not
being pursued in an integrated, systematic manner. The act requires that ongoing water quality assessments be
conducted for each river basin in Texas, an approach that integrates water
quality issues within the watershed. The CRP Legislation mandates that “each
river authority (or local governing entity) shall submit quality-assured data
collected in the river basin to the commission.” “Quality-assured data” in the
context of the legislation means “data that complies with commission rules for
water quality monitoring programs, including rules governing the methods under
which water samples are collected and analyzed and data from those samples are
assessed and maintained.” This QAPP addresses the program developed between the
SRA and the TNRCC to carry out the activities mandated by the legislation. The QAPP was developed and will be
implemented in accordance with provisions of the Quality Management Plan for
the Clean Rivers Program (most recent version).
The purpose of this QAPP is to clearly delineate SRA QA policy,
management structure, and procedures, which will be used to implement the QA
requirements necessary to document the reliability and validity of
environmental data. The QAPP is
reviewed by the TNRCC to help ensure that data generated for the purposes
described above are scientifically valid and legally defensible. This process will ensure that data collected
under this QAPP and submitted to the state-wide database have been collected
and managed in a way that guarantees its reliability and therefore can be used
in water quality assessments and other programs deemed appropriate by the
TNRCC. Project results will be used to
support the achievement of Clean Rivers Program objectives as contained in the
Clean Rivers Program Guidance and Reference Guide FY 2002 -2003.
The SRA Environmental
Services Division (ESD) collects surface water quality data as part of its
commitment to water quality protection in the Sabine Basin. This Water Quality Monitoring Program (WQMP)
includes fixed station monitoring and analyses of physical, chemical,
bacteriological, and biological parameters.
SRA also conducts special investigations concerning pollution
complaints.
Additional monitoring
requirements have been brought about through the implementation of the
TCRP. This additional systematic
monitoring program complements the existing fixed station monitoring by
providing information on the many subwatersheds not covered by the fixed
station monitoring. The systematic
monitoring utilizes biological screening studies in combination with routine
physical and chemical parameters to provide data on the health of aquatic life
and long-range water quality protection.
The systematic monitoring also includes field investigations to provide
data on subwatersheds, which have never been sampled.
The basin topography has
been used to divide the Basin into 110 subwatersheds (24 of these are located
in Louisiana), which are organized into 7 reaches. A ‘reach’ of the main-stem of the River roughly corresponds to
the old segment system but the reaches are based on hydrography and similarity
of land features. This system allows a
manager to determine which areas have adequate water quality information and
which areas do not. The subwatershed
approach also incorporates risk factors such as municipal and industrial
outfalls, solid waste sites, urban and rural land use, etc., into the decision
making process.
Water quality data is
analyzed using the data analysis program developed by SRA following guidance
from the TNRCC. The fixed station and
systematic programs are reviewed each year to consider revisions in every
aspect of the programs.
The 1999 TCRP Sabine Basin Summary Report identified subwatersheds with
water quality concerns in the Sabine Basin.
The areas were prioritized using input from the Sabine Basin Steering
Committee and the SRA staff. Monitoring
plans were developed by the SRA and other monitoring partners in cooperation
with TNRCC staff at the annual coordinated monitoring meetings to address these
priority Subwatersheds.
SRA will conduct monitoring at
fixed monitoring sites to adequately characterize water quality trends and
monitor progress in protecting or restoring water in the Sabine Basin. All monitoring plans are coordinated with
the TNRCC regional offices to avoid duplication of effort. The fixed monitoring sites include 30 - 40
sampling sites that are monitored monthly for routine physical and chemical
parameters. Selected sites are also
monitored annually for metals in water and metals in sediment. Details of the monitoring schedule,
parameters, and sampling locations are included in Appendix B.
SRA will conduct systematic
monitoring utilizing biological screening studies in combination with routine
physical and chemical parameters.
Approximately seven sites will be monitored in FY 2002 and four to six
sites will be monitored in FY 2003. Details of the monitoring schedule, parameters,
and sampling locations will be included in Appendix B. The water quality data includes
monitoring and analyses of physical, chemical, bacteriological, and biological
parameters. Instantaneous flows will be
collected at selected sites. These
programs provide data on the health of aquatic life and long-range water
quality protection.
Special studies will be
conducted in the Caney Creek Subwatershed to determine impacts due to changes
in effluent loading. A non-point study
will continue in the Grace Creek Subwatershed to delineate concerns identified
in the 1999 assessment. The Rabbit
Creek and Hawkins Creek Subwatersheds are scheduled for special studies to
determine non-point impairments.
See
Appendix A for the project-related work plan tasks and schedule of deliverables
for a description of work defined in this QAPP.
See Appendix B for
details on monitoring to be conducted under this QAPP. The TNRCC monitoring sites are included only
for the purposes of showing coordinated basin monitoring and are addressed by
the TNRCC Surface Water Quality Monitoring (SWQM) QAPP.
Amendments to the QAPP
Revisions to the QAPP may be necessary to reflect changes in project
organization, tasks, schedules, objectives, and methods; to improve operational
efficiency; and to accommodate unique or unanticipated circumstances. Requests for amendments are directed from
the SRA Project Manager to the CRP Project Manager in writing. They are effective immediately upon approval
by the SRA Project Manager, the Planning Agency QAO, the CRP Project Manager,
the CRP Lead QA Specialist, and the CRP Project QA Specialist. They will be distributed by the SRA Project
Manager and incorporated into the QAPP by way of attachment and distributed to
personnel on the distribution list.
Appendices to the QAPP
Appendices as referenced under the Project Description above will be
submitted as work is planned. Projects requiring QAPP appendices will be planned in consultation with the SRA
and the TNRCC Project Manager and TNRCC technical staff. Appendices will be written in an
abbreviated format and will reference the Basin QAPP where appropriate. Appendices will be approved by the SRA
Project Manager, the SRA QAO, the CRP Project Manager, the CRP Project QA
Specialist, the CRP Lead QA Specialist and other TNRCC personnel as
appropriate. Copies of approved QAPPs
appendices will be distributed by the SRA to project participants before
monitoring activities are commenced.
The purpose of fixed/routine water quality monitoring is to collect
surface water quality data needed for
conducting water quality assessments in accordance with TNRCC’s Guidance for
Assessing Texas Surface and Finished Drinking Water Quality Data. These water quality data, and data collected
by other organizations (e.g., USGS, TNRCC, etc.), will be subsequently
reconciled for use and assessed by the TNRCC.
No decisions will be made by the project team based on the data
collected.
The measurement performance criteria to support the project objectives
for a minimum data set are specified in Table A7.1. The SRA Laboratory will perform all of the analyses listed in
Table A7.1.
