AUTHORIZATION LETTER
Regional Storm Water Management Program
of North Central Texas:
FY2001 Regional Storm Water Monitoring Assistance
United States Geological Survey (USGS)
And Local Laboratory
The NCTCOG and the City of Fort Worth(hereafter referred to as the"participant") have executed an
Interlocal Agreement to provide a structure through which the participants can pursue initiatives that assist with
Federal NPDES storm water permit requirements including cooperative regional wet weather monitoring. The
Interlocal Agreement established a structure by which a Regional Storm Water Management Coordinating
Council may identify specific activities to be carried out by NCTCOG, and/or other professional agencies, with
cost allocations to be determined through Coordinating Council consensus.
On behalf of the NPDES Phase I entities, NCTCOG has coordinated the design of a cooperative Regional Storm
Water Monitoring Program that has been formally endorsed by the United States Environmental Protection
Agency (USEPA), Region 6. The cooperative sampling program is designed to meet the storm water
monitoring requirements for each individual permit holder, while providing for a more efficient, consistent and
cost-effective regional effort. The USGS Sampling Program through September 2001 has been outlined, and
cost share arrangements have been approved by the Coordinating Council for the USGS/local lab agreement.
Attachment A of this Authorization Letter is a table outlining the sites to be sampled and the tentative schedule
for accomplishing storm water monitoring of site events during FY2001. This form seeks funding commitments
and authorization to proceed with the scheduled storm water sampling. Attachment B is a copy of the USGS
Work Program which outlines the specific tasks and responsibilities of the USGS and participating entities
related to sampling and analysis during the forthcoming fiscal year. Attachment C is a copy of the USGS Work
Program which outlines the tasks of USGS related to the Evaluation of Storm Water Monitoring Data and
Network project. Attachment D is a table outlining the cost share arrangements among all participants for the
USGS assistance with Regional Monitoring Program, the additional local laboratory analytical costs that will be
incurred, and the Storm Water Monitoring Data and Network Evaluation to be performed by USGS. NCTCOG
will enter into a phased Joint Funding Agreement with the USGS and a local laboratory for monitoring
assistance and analysis on behalf of the participating permit entities, whereby the USGS will collect storm water
samples from storm events as part of the permit requirement for an ongoing assessment of urban storm water
quality in the Metroplex and the local laboratory will conduct the analysis of these samples.
In accordance with Article 2, Paragraph 5, and Article 4 of the Interlocal Agreement, the purpose of this letter is
to authorize the participant's share of the FY2001 Work Program for Storm Water Monitoring Assistance which
is as follows:
a. USGS FY2001 Monitoring Assistance (Sampling and Analysis) in the amount of: $ 52,333
b. USGS Evaluation of Storm Water Monitoring Data and Network in the amount of: $ 3,125
c. Local Laboratory analysis of samples in the amount of: $ 5,509
Total Amount $ 60,967
00,P I cc�A, kECC_0�D
Execution of this Authorization Letter is considered a formal part of the Interlocal Agreement, and obligates the
participant's cost share as identified above. Billing of the participant by NCTCOG for these services will be
made no more frequently than monthly, and will be based on the prorated share of deliverables received by the
participants. NCTCOG will invoice the participant for its costs incurred resulting from the FY2001
work program, and the participant shall remit the amount of the invoice to NCTCOG within thirty (30)
calendar days of receipt of the invoice. In the event that the participant does not accept the goods or services
or finds an error in the invoice,the participant shall notify the NCTCOG Senior Environmental Planner who is
responsible for executing this program as soon as possible within the 30 calendar day period, and shall make
payment not less than ten (10) calendar days after the problem(s)are corrected or the error is resolved to the
satisfaction of all parties. In the event that payment for invoiced goods or services is not received by the
NCTCOG within 30 calendar days of receipt of the accepted invoice, NCTCOG is authorized to charge the
participant interest in accordance with the Prompt Payment Act.
Work under this program may continue beyond September 30, 2001,to complete the authorized FY2001 work
program. However,costs for the work program will not exceed the participant's cost share as agreed to in this
authorization letter.
The undersigned,duly authorized to make such obligations, represent NCTCOG's and the City of Fort
Worth's agreement to these provisions.

Storm Water Sampling and Analysis
Problem
The seven largest cities in the Dallas-Fort Worth Metroplex and the Texas Department of Transportation
(TxDOT), Dallas and Fort Worth District Offices, have been issued permits from the U.S. Environmental
Protection Agency (USEPA)for the discharge of storm water runoff to receiving waters of the United States.
As part of the permit requirements, a regional monitoring program has been developed under the
coordination of the North Central Texas Council of Governments (NCTCOG)on behalf of the permitees.
The program includes continued storm water quality sampling from storm sewer outfalls draining small,
single land-use basins that were used to characterize water quality as part of the permit application phase and
establishing new monitoring stations at storm sewer outfalls draining larger, more diverse land-use basins,
and at several instream locations. The U.S. Geological Survey has agreed to assist the seven municipalities
and TxDOT in meeting the requirements of this monitoring program.
Objectives
The principal objective of this study is to fulfill the requirements of the Dallas-Fort Worth regional storm
water monitoring program for the five-year permit term. These requirements include monitoring storm water
runoff and characterizing storm water quality.
Approach
This study will be conducted during the permit term(5 years)and will begin on or about October 1, 1996.
The monitoring program will be reviewed and modified, if necessary, by the NCTCOG regional storm water
committee (NCTCOG staff, permittee representatives, and the USGS) and negotiated with the USEPA(if
necessary) on an annual basis. Costs to meet the objectives of this study will be determined annually.Tasks
to meet the objectives are as follows:
(1) Collect storm-water samples from the storm-sewer outfall network of 22 stations. Samples will be
collected at each station according to the approved regional schedule.
(2) Collect storm rainfall and runoff data and data on antecedent conditions for each station.
(3) Perform laboratory analyses (either directly or via a private local laboratory) of selected water-quality
constituents and properties (Target Regional Parameter List)as listed in Table 1. Laboratory analyses
include QA/QC samples.

Reports
A complete set of all data collected during each permit year will be provided to NCTCOG. Water Fact sheets
and journal articles may be prepared, as appropriate,to describe and document data collection,characterize
the quality of storm-water runoff.
Equipment
All equipment and instrumentation that were used at the storm-water stations to collect data during the
permit application phase(1991-93) will continue to be used for this project. Thirt=y sets of equipment and
instrumentation are available for the 22-station network planned for this project.
The equipment and instrumentation cited above were purchased by the USGS;thus, current ownership is
with the USGS. As stated in the original project proposal(scope of work) dated April 15, 1991, ultimate
ownership of the equipment and instrumentation in place at the storm-water stations is with the permittees
(the seven municipalities and TxDOT). Ownership of this equipment is retained by the USGS until such
time as individual permittees request a transfer of ownership. Upon transfer of ownership, the permittee
assumes all responsibility for operation, maintenance,repair and replacement of all equipment and
instrumentation associated with the stations located within their jurisdiction.

Evaluation of Storm Water Monitoring Data
and Network in North Central Texas
Background and Problem
The Federal Water Pollution Control Act of 1987 required the Environmental Protection Agency (EPA)
to establish National Pollutant Discharge Elimination System (NPDES) requirements for various classes
of storm water discharges, including Municipal Separate Storm Sewer systems(MS4). In 1990, EPA
issued regulations that required cities with over 100,000 population and other major operators of storm
sewer systems to obtain storm water discharge permits.The permit applications required the
characterization of the quantity and quality of the storm water from watersheds within their respective
jurisdictions. Seven municipalities(Dallas,Fort Worth, Arlington, Irving, Garland,Plano and Mesquite)
and two local Districts of the Texas Department of Transportation were impacted by the rules and joined,
through the North Central Texas Council of Governments(NCTCOG), in a regional cooperative program.
In conjunction with the regional program, NCTCOG entered into agreement with the U.S. Geological
Survey (USGS)to establish a monitoring network of 30 stations,each station monitored a predominate
land use (residential,commercial, industrial, and highway)for the application phase (1992-1994). In
preparation for the permit term sampling, a network analysis was conducted by the USGS to evaluate the
data and to reduce station redundancy. The network was subsequently reduced to 15 of the original
stations and 7 new stations were added to look at discharges from mixed land use, in-stream, and
undeveloped. This configuration of station monitoring was used during the initial 5-year permit term
(1997-2001). During the period of February 1992 to June 2000, hundreds of samples have been collected
for the NPDES permit application phase and the five-year regional wet weather monitoring program.
However, it is unknown whether water-quality changes have occurred at the sample collection sites, if a
reduction in sampling sites or samples is warranted for the next permit term,and if the existing sampling
sites are spatially representative of the major north central Texas watersheds as a whole.
Objectives and Scope
The objective of this project is to evaluate the existing storm-water data and NCTCOG network to
propose scientifically defensible alternatives for future NPDES data collection efforts.
Approach
The objectives of this study will be accomplished by completing the following tasks:
1. Review historical NPDES data and determine suitability for inclusion in network analysis.
2. Evaluate land use, watershed and jurisdictional boundary data using a Geographic Information
System (GIS) to identify representative watershed boundaries in the north central Texas area.
3. Conduct a statistical network evaluation to determine if differences in selected properties or
constituents exist between land-use types; have occurred over time for individual sites; or exist
between sites with the same land use.
4. Propose scientifically defensible alternatives for future NPDES data collection efforts.

Task 1–Review and Selection of Data
A determination will be made as to which properties and constituents will be evaluated in the network
analysis. Water-quality and-quantity data collected from the NCTCOG network will be reviewed and
representative data will be selected for use in the network analysis.
A cursory review of the USGS National Water Quality Lab(NWQL)data and the Armstrong lab will be
conducted. Replicate samples will be used to compare samples independently analyzed by each lab.Only
7 samples are currently available to conduct this comparison.A report on the Armstrong lab's analyses of
standard reference samples,part of the NWQL's Analytical Evaluation Program, will also be examined.
The report should be out in September, 2000,provided there are no major problems in the results.
Task 2–Geographical Information System(GIS)Evaluation
GIS land-use, watershed, and jurisdictional boundary data will be provided by NCTCOG to the USGS.
These data will be used to evaluate the spatial distribution and representativeness of existing network
sampling sites based on watershed and jurisdictional boundaries, and land-use.If historical land use data
are available from NCTCOG, land use changes through time will be evaluated to determine potential
impacts on storm water data collected at historical and existing network sites.These changes would also
provide insight as to where growth is expected in the next 5-10 years in the metroplex area.
Task 3–Statistical Evaluation of Existing Data Network
Use statistical tests to analyze for changes in storm water quality—unit loads and event mean
concentrations of selected constituents.
A. Test for differences in storm water quality between or among in-stream,mixed, and the various
predominate land use types(industrial,commercial,residential, and highway).
B. Test for changes in storm water quality over time for the 15 predominant land-use sites that have
data over the longest time period(1992-1994,and 1997-2000).
C. Test for differences in storm water quality between or among stations with the same land-use type.
Task 4–Development of Data Network Alternatives
The USGS will propose alternatives,which are scientifically defensible, for future NPDES data collection
efforts based on Tasks 1-3.Alternatives will be presented and rationale given for proposed network and
data collection design.
Task 5–Preparation of Report
Compile report sections,prepared as parts of Tasks 1-4,add necessary components,and submit to
supervisor for review process. Revise report,as needed,and resubmit for each step in review process until
report is approved and printed.
Quality Assurance Project Plan
No new data will be collected but rather a review of existing data will be conducted.Historical storm
water data will be reviewed via: plotting of hydrographs and aliquot collection,evaluation of rainfall and
theoretical rating data,evaluation of procedures followed when compositing samples,tracking of
laboratory sample documentation, and looking for data entry errors.
Benefits
This project will provide an evaluation of storm water data and network associated with one of the largest
NPDES programs in the U.S. Results from this evaluation will have transfer value to NPDES programs
located across the U.S. (i.e. cities with populations greater than 100,000).
Products
The products from this project are a draft USGS Water Resources Investigation Report (WRIR) presented
to the cooperator by mid-January 2001 and a WRIR published by September 2001.

* Cost-shares for municipal participants are determined by allocating one half of the total program cost by population and
one half on equal portions among the 7 municipal participants. Cost-shares for TxDOT are determined by considering
them as a participant with no population. The total TxDOT cost-share is therefore 1/8'h of the project cost, with each
respective district contributing one half of that amount. TxDOT Dallas contributes an additional amount to pay for an
extra monitoring site.
** Each municipal participant's cost share is 1/8 h of the Data and Network Evaluation project cost. TxDOT's share is also
1/8 0'of the project cost, split equally between the Dallas and Fort Worth Districts.

SUBJECT APPROVAL OF INTERLOCAL AGREEMENT WITH THE NORTH CENTRAL TEXAS
COUNCIL OF GOVERNMENTS FOR THE REGIONAL STORM WATER
MANAGEMENT PROGRAM
RECOMMENDATION:
It is recommended that the City Council approve the FY2000-2001 amendments to the Interlocal
Agreement with the North Central Texas Council of Governments (NCTCOG) for FY2000-2001
administrative support and storm water monitoring assistance as part of the regional storm water
management program in the amount of$83,425.00.
DISCUSSION:
Storm water regulations included in the Clean Water Act pose significant impacts for seven Metroplex
cities (Fort Worth, Dallas, Arlington, Garland, Irving, Plano and Mesquite) and the Texas Department of
Transportation. For the past several years, representatives from these entities have worked together
through the NCTCOG's Regional Urban Storm Water Management Task Force in preparation for
meeting storm water permit requirements. Because all of the entities are required to implement many
of the same programs, the potential for cost sharing and coordination of programs exists.
In November 1993, the City entered into an Interlocal Agreement with the NCTCOG to cover
administrative support for regional initiatives undertaken during FY1993-1994. This agreement was
renewed on October 25, 1994 (M&C G-10848) for FY1994-1995, on April 9, 1995 (M&C C-15380) for
FYI 995-1996, on April 15, 1997 (M&C C-15991) for FYI 996-1997 and on April 7, 1998 (M&C C-16719)
for FYI 997-1998.
In addition, an amendment to the agreement;approved on January 9, 1997 (M&C C-15839), provided
for storm water monitoring assistance from the U.S. Geological Survey (USGS) for FY1996-1997. The
FY1998-1999 amendments were approved on November 3, 1998 (M&C C-17095). The FY1999-2000
amendments were approved on October 19, 1999 (M&C C-17708).
The current agreement covers an estimated $22,458.00 allocated as the City of Fort Worth's share of
administrative costs to be incurred by NCTCOG during FY2000-2001 in support of the Regional Urban
Storm Water Management Task Force, its associated sub-committees, and the USGS Cooperative
Monitoring Program.
Storm water monitoring assistance will be in the form of sampling and analysis of storm water runoff
and the related reports of findings. NCTCOG will contract with the USGS to provide staff, equipment
maintenance, Quality Assurance/Quality Control protocols, and storm water characterization through
sampling and laboratory analysis for FY2000-2001 at a cost of$60,967.00.
Total cost to the City of Fort Worth for these activities is $83,425.00.
