Dear Mr . Gill :
The City of Wylie is in receipt of a letter from your office
dated May 14 , 1666 wherein you make reference to an annual
compliance inspection of the City of W'ylie ' s wastewater
treatment plant permit No . WQ00103 4-UD1 . It is our
intention to respond in detail to the comments offered in
that letter within the period ( 45 days ) specified . The
purpose of this letter is to acknowledge receipt of your
letter and return initial comments to some of your remarks .
Your letter begins by noting deficiencies in Section A ,which
are labeled " Wastewater Treatment Plant Maintenance" . These
comments number 1 through 6 . In addition , your office
comments deficiencies in the "wastewater treatment plant
operation" your Section B and these comments number 1
throuch 8 . While you personally may not be aware of this ,
the City wishes to inform your office that while the City
knows and understands that it retains legal responsibility
for the operation of this plant and it ' s compliance with all
laws . We do have a contract with North Texas Municipal
Water District for the operation and maintenance of that
plant . Therefore , I shall share these comments with the
Council of the City of Wylie as well as forward a copy of
this correspondence to NT,i'UD for their response . It is our
position that they and they alone are responsible for the
deficiencies in this area .
Under your comments Section C " Industrial Waste Honitorin
end Enforcement " , numbers 1 through S , the City offers these
initial comments . The City of ! ylie passed it ' s first
wastewater control ordinance in 1 5% 2 . As was the case at the
time , this ordinance dealt almost exclusively with heavy
metals and was not a modern ordinance of any type at all .
In July 1965 , the City passed a modern wastewater and water
pollution control and abatement ordinance . The first step
1
in applying this ordinance has been to distribute
questionaires to the local businesses and potential
polluters for their voluntary response . This step has been
taken . In addition , the City is contacting several chemical
testing laboratories to make arrangements for acceptable
samples to be taken so that they may be used as part of our
enforcement program . It was necessary for us to locate and
contract with a private firm since NTMWD , the body who
normally does our testing , refuses to appear in court to
testify about the results of their analyses . Once these
steps are completed , your office will see an effective
enforcement program .
In item 2 of this section , you list a troublesome grab
sample in the SOD was high . In the second part of that
paragraph , you talk about " new connections , increased flows ,
or significant changes " causing a change in the influent
quality which apparently relates to the high BOD you
mentioned earlier . It is our belief that the high BOD ' s are
a result of blood entering the system from three potential
sources . None of these sources are new . All of our growth
has been almost exclusively in standard housing producing
ordinary domestic wastewater . In addition , we are curious
why this change has not been reflected in the monthly
reports for the operation of the plant . lie :an only assume
that the sewage treatment plant is effectively dealing with
this problem or the reports are in error .
In Section D System Bypasses , you note an incidence where an
overflow occured not a bypass which implies intent . In that
section , you speak of a grab sanple and your concern about
Muddy Creek . As a result of this incident , an earthen dam
was erected around the tanks which would automatically
return any future occurance of this nature back into the
tanks and would not allow any physical means by which this
discharge could enter Muddy Creek . Further in the paragraph
you speak about our obligations to notify you concerning any
discharge . It is my understanding that this has been done
promptly and to an extent to which I have never seen in any
community that I have served prior to this . Of particular
interest to me was the fact that a bypass was done by NTiiUD
and was reported to your office . It is my belief that this
bypass was intentional and was reported to your field
representative along with a sample of what hhdT ' ''ID claimed was
a back-wash . It should be noted that this back-wash
2
contained raw sewage . I was an eye witness to this incident
along with several other people who .Jouid be happy to
testify . Yet I find no mention of this incident in the
report .
In item 2 of that section , you discuss the reviewing
authority rights of the Texas Water Commission . I would
like to point out that none of our system improvements have
participation by Federal or State agencies . They are
financed exclusively with local funds , developers costs or
charged fees . In addition , while this requirement is , I
believe , being unusually enforced , we have complied and have
submitted all of our plans for lift stations and sewer lines
to the appropriate authorities , many of them have been
returned approved . We have had no indication that any of
our improvements will not be acceptable .
In Section E you discuss a troublesome grab sample . We are
curious why a grab sample is fine here when your own rules
seem to indicate a preference for composite s =_nples . be are
also curious how we have been able to pre _uce such good
reports .
In Section F , you make comment concerning several design
deficiencies of the plant . These comments will be forwarded
to NTiNWd for their response , for it is a requirement of
their contract that they notify us of any alterations or
improvements that may need to be made from time to time in
the plant . I an enclosing a copy of that agreement as well
as several other documents . You should be aware that the
City of ylie has advertised for consultant engineering
services for modifications to it ' s existing plant and design
of a new wastewater plant to meet more nocern treatment
guideline_ using current technology . have narrowed that
process down to the final three firms . These firms are CH2W1
Hill , Brown & Caldwell and Riewe & Wischneyer . The City was
prepared to select one of these firms and begin the design
phase . However , we have responded to a request from NTi:'bD
that has delayed that process .
In Section G , you comment about a report that is missing . I
will be happy to inform bT1UD that you require this -. eport .
You attached a letter dealing with the temporary lift
station . That lift station was placed by a developer and we
have always admitted it did not meet the standards . The
City has since replaced this temporary station .Jitin a system
that does meet the design criteria . This same comment eculd
be appropriate to the letter that you attache dated January
1oc .
I trust that these comments , which will be ._ ' ared with the
City Council , NTL:CD , your district office a^ d Austin will
provide some initial response to your corimelts while we
oeepare a much more lengthy and technical response . In
addition , it is my belief that many of these problems will
be solved within that period since that process was already
at work . Please contact this office shoule you require
clarification of any of these preliminary comments .

THE NORTH TEXAS MUNICIPAL WATER DISTRICT FOR WASTE-
WATER TREATMENT PLANT OPERATION.
This contract, made and entered into as of the day of
, 1974 by and between the North Texas Municipal
Water District, hereinafter called "District", and the City of Wylie, Texas, a
municipal corporation in Collin County, Texas, hereinafter called "City"
WITNESSETH:
WHEREAS, City owns and operates a wastewater treatment plant which
discharges into a tributary of Muddy Creek downstream of Highway 78, and
WHEREAS, City has a permit from the Texas Water Quality Board to
discharge an average amount of 150,000 gallons per day of treated waste into
a tributary of Muddy Creek in the vicinity of the existing plant, and
WHEREAS, District has been designated by the Texas Water Quality
Board to function as a regional agency in connection with the design, construc-
tion and operation of systems in the area tributary to the East Fork of the
Trinity River in the Counties of Dallas, Collin, Rockwall and Kaufman, and
WHEREAS, both City and District recognize the imminent necessity of
treating waste to the degree necessary to allow its safe reuse for water supply
and other purposes, and
WHEREAS, District, because of its water supply responsibilities and
the capability to contract with others in the region, appears to be in the best
position to fully develop the potential for advanced treatment and reuse in
the East Fork area;
- i -
NOW THEREFORE, in consideration of the mutual covenants and agreements
herein contained, District agrees to operate the existing plant and City agrees
to pay for such service upon the terms and conditions hereinafter set forth, to-wit:
I . Operating Responsibility. It is the intent of this agreement that the
operation of the plant shall be the responsibility of the District and that the
plant shall be operated in a manner that will provide a water quality conforming
to the waste control order issued by the Texas Water Quality Board, or any subse-
quent order issued relating to this plant.
2. Financing. The olant is presently owned by the City, and it shall be
City's responsibility to provide such facilities, operating funds, and capital
expenditures as are necessary to accomplish the quality of discharge stipulated
in the waste control order issued by the Texas Water Quality Board, or any subse-
quent orders. At an appropriate time and under terms agreeable to both parties
City will transfer ownership of the plant to District in order that it may be
incorporated in a regional system.
3. Operating Budget. The District shall prepare an annual operating
budget reflecting all anticipated costs In connection with the operation of the
plant in sufficient detail to justify expenditures for salaries, materials,
supplies and contractual services. The proposed operating budget shall be sub-
mitted to City on or before August I of each year. If no protest or request
for a hearing on the Budget is not presented prior to September I , the proposed
Budget, on adoption by the District, shall be considered the "Annual Budget"
for the ensuing fiscal year.
In the event City and District are not able to agree on the operating
budget prior to October I , the budget for the previous year shall apply for the
first 60 days of the new fiscal year, with adjustments only to those items that
are agreed to by City. If, at the end of this 60 day period, no agreement has
- 2 -
been reached on the operating budget this contract shall be terminated in
accordance with the termination provisions herein provided.
In first year a budget will be prepared for a full twelve ( 12) months
with payments based thereon, but on the next October a new Budget will be imple-
mented and fiscal year shall thereafter be October I to September 30 of each year.
4. Annual Charges. Monthly payments shall be made by City equal to the
total operating budget divided by 12, and these payments shall be made in advance
on or before the 10th day of each month. The first monthly payment due October 10
of each year shall be twice the calculated monthly payment with no payment due in
September of each year except for any adjustments previously approved by City. At
the end of each fiscal year any surplus balance would be carried forward to reduce
the overall cost during the next budgetary period.
Emergency expenditures not budgeted may be incurred with the concurrence
of the District's Executive Director and the City's City Manager, subject to
limitations placed on each by respective governing bodies, with appropriate adjust-
ments in monthly payments. Routine requests for adjustments in monthly payments
must receive prior approval by the City.
In the event the City shall fail to make any monthly payment by the
20th day of the month in which due, after notice to City, the District may termi-
nate service as of the first day of the following month.

palities subject to approval of City, and the charge which is levied for such ser-
vice shall include adequate compensation to the City for its capital investment as
well as operating expenditures.
. 6. Termination. Either City or District may require that this operational
agreement be terminated. The party desiring to terminate this agreement shall sub-
mit notice in writing to the other party, after which a period of 30 days shall be
- 3 -
allowed before termination becomes final . Once this agreement is terminated Dis-
trict shall continue its operating responsibility for a period of 45 days at the
request of City.
7. Industrial Waste. City agrees to enforce its industrial waste
ordinance and to take such action as is necessary to control the strength of raw
sewage reaching the plant in order that the quality of discharge required in the
waste control order may be maintained.

9. Indemnity. City agrees to indemnify and hold harmless the District
from any and all causes for loss, liability, or damages arising out of the opera-
tion of the plant by the District except for acts of negligence by District person-
nel . The City further agrees to maintain adequate fire and extended coverage
insurance on said plant.
10. District's Financial Obligation. Nothing in this agreement shall be
construed as requiring the District to expend funds from any source other than the
revenues received hereunder. All cost required by valid rules, regulations, laws
or orders passed or promulgated by the United States of America, the State of Texas,
and regulatory or judicial branches thereof having lawful jurisdiction shall be the
responsibility of the City.

RE: The Wylie Wastewater Treatment Plant
Annual Compliance Inspection
Permit No. WQ0010384-001
Dear Mayor Hughes:
On March 13, 1986 and April 4, 1986, our representative, Mr. Forrest
B. John, conducted an annual compliance inspection of the City of
Wylie Wastewater Treatment Plant (WWTP) and Collection System. During
the inspection, numerous deficiencies were noted and are itemized below
for your convenience.
A. Wastewater Treatment Plant Maintenance
1 . The wastewater treatment- plant lift station pumps were leaking
due to faulty packing.
2 . The surface of the clarifier was covered with a layer of sludge.
Activated sludge was washing over the clarifier weirs .
3 . On the date of the inspection, no chlorine residual was present
in the plant effluent. Solids, from recurrent plant upsets,
accumulate in the chlorine contact basin and enter chlorinators
with make-up water. This results in the chlorinators becoming
clogged.
4 . Approximately half of the chlorine contact basin surface was
covered with a sludge blanket. Due to sludge in the basin,
solids were washing out of the basin with the effluent.
5 . One of the two sludge return pumps was in need of repair.
6 . Valving at the diversion box, ahead of the effluent pipe, was
deteriorated to a point where the valves can no longer be
opened or closed.
B. Wastewater Treatment Plant Operation
1 . Sludge disposal records are not being maintained.

2 . For self-reporting purposes, the effluent has been sampled
by the individual grab samples rather than the required
3-part composite sample.
The Texas Administrative Code 329 . 9 (a) Table 1 , 0 . 50 - 1 .0
MGD, Design Capacity, states :
"The laboratory test shall be made on a composite sample
made up of three proportions collected no closer together
than 2 hours and with the first sample collected no earlier
than 10 :00 a.m. "
3 . Improper removal of solids from the chlorine contact basin.
C. Industrial Waste Monitoring and Enforcement Program
1 . City of Wylie industrial waste monitoring and enforcement is
nonexistant.
2 . The influent wastewater individual grab sample, collected March
26, 1986 , analytical results are as follows:
(a) pH (standard units) 7 .7
* (b) Biochemical Oxygen Demand 1,053
(c) Total Suspended Solids (mg/1) 185
*Typical Biochemical Oxygen Demand (5-day) values for
untreated domestic wastewater are approximately 250 mg/l .
Item 1 . (d) under "General Conditions" , of Permit No. WQ0010384-001
states :
"d. Any change in the facility discharge, including
any new significant discharge or significant changes
in the quantity or quality of existing discharges to
the treatment system that will result in new or increased
discharges of pollutants must be reported to the permitting
authority. Modifications to the permit may then be
made to reflect any necessary changes in permit condi-
tions , including any necessary effluent limitations for
any pollutants not identified and limited herein. In no
case are any new connections, increased flows, or sig-
nificant changes in influent quality permitted that will
cause violation of the effluent limitations specified
herein. "
3 . The City of Wylie has failed to monitor industrial waste
discharges into the sanitary sewer system while fully cognizant
that the industrial discharges were having a direct and detri-
mental impact upon the wastewater treatment plant.

D. The Wastewater Treatment Plant Collection System and Collection
System Bypasses
1 . On March 13 , 1986 , the Texas Water Commission District 4
Office received an anonymous complaint of alleged frequent
wastewater bypasses occuring at the Southfork Mobile Home
Park Addition. In response, on March 26 , 1986 , Mr. Forrest
B. John of this office conducted an on-site investigation
accompanied by Mr. W. W. Windham, City of Wylie Director of
Public Works . During the investigation, what appeared to
be a recent wastewater bypass from the wastewater holding
tank at the Southfork Mobile Home Park was observed. The
discharge flowed to an unnamed tributary of Muddy Creek
located approximately 250 feet northeast of the wastewater
holding tanks . A grab sample was obtained. Analytical
results of the grab sample are as follows: (COC Tag No.
IN 17344)
a. pH (standard units) 8 . 3
b. Biochemical Oxygen Demand (mg/1) 128
c . Total Suspended Solids (mg/1) 100
d. Ammonia-Nitrogen (NH3-N) , (mg/1) 23 . 30
The results of the grab sample confirms that the suspected
wastewater exhibited the typical composition of untreated
domestic wastewater. Therefore, unreported wastewater
bypass appears to have occured that entered the unnamed
tributary of Muddy Creek. The District 4 Office has advised
the City of Wylie, by letter on two previous occasions
(September 1985 and January 9 , 1986 copies attached) of
reporting procedures for wastewater bypasses .
Please be advised that Chapter 26 . 039 (b) , 26 .121 (a) and
26 .126 (a) and (b) of the Texas Water Code states:
26 .039 (b) "Whenever an accidental discharge or spill
occurs at or from any activity or facility which
causes or may cause pollution, the individual opera-
ing, in charge of, or responsible for the activity
or facility shall notify the commission as soon as
possible and not later than 24 hours after the
occurence II
26 . 121 (a) "Except as authorized by a rule, permit or
order issued by the commission, no person may:
(1) discharge sewage, municipal waste, recreational
waste, agricultural waste, or industrial waste into or
adjacent to any water in the state;
(2) discharge other waste into or adjacent to any
water in the state which in itself or in conjunction
with any other discharge or acitivity causes, continues
to cause, or will cause pollution of any of the water
in the state; or
City of Wylie
Permit No. WQ0010384-001

Page 4
(3) commit any other act or engage in any other
activity which in itself or in conjunction with any
other discharge or activity causes, continues to
cause, or will cause pollution of any of the water
in the state, unless the activity is under the
jurisdiction of the Parks and Wildlife Department,
the General Land Office, or the Railroad Commission
of Texas, in which case this subdivision does not
apply. "
26 .126 (a) If a person violates this chapter or a
rule or order adopted or a permit issued under this
chapter, the commission may assess a civil penalty
against that person as provided by this section.
(b) The penalty may be in an amount not to exceed
$10, 000 a day for a person who violates this chapter
or a rule, order, or permit. Each day a violation
continues may be considered a separate violation for
purposes of penalty assessment. "
In addition, the City of Wylie, Texas Water Commission Permit
No. WQ0010384-001, Item 11, under "General Conditions" states :
"The permittee shall within 72 hours notify the permit
issuing authority in writing of each unauthorized diver-
sion or bypass in accordance with the procedure specified
for reporting noncompliance. "
2 . The Wyndham Estates and Southfork Mobile Home Park Collection
systems have not been approved by the Texas Department of
Health.
Please be advised that the Texas Administrative Code Chapter
317 .1 (a) (2) and 317 .1 (a) (3) (F) state:
317 .1 (a) (2) Reviewing Authority. The Texas Water Code
places the responsibility with the Texas Water Commission
for review of plans and specifications for construction
projects funded by the Texas Water Quality Enhancement
Fund. The commission will also review all plans for
projects which may receive United States Environmental
Protection Agency financial assistance under the
Construction Grants Program The Texas Department
of Health will review all plans and specifications for
work that is not eligible for federal or state financial
assistance, and for all projects that are funded
exclusively under Farmers Home Administration, Economic
Development Administration, and Department of Housing
and Urban Development. The Texas Water Commission and
the Texas Department of Health are hereinafter referred
to as the Reviewing Authority for projects within their
respective jurisdiction.

317 .1 (a) (3) (F) Changes or Alterations. When changes
are planned for existing systems, notification to the
reviewing authority shall be made and shall include
sufficient information to describe the significance
of such modifications . The reviewing authority will
determine whether engineering plans and specifications
will be required following this initial notification
of the extent of the planned modifications . "
In addition, Item 4 , under "Other Requirements" of Permit
No. WQ0010384-001 states :
"4 . The plans and specifications for the waste
collection and treatment works associated with the
discharge authorized by this permit must be approved
pursuant to state law, and failure to secure approval
before commencing construction of such works or making
a discharge therefrom is a violation of this permit
and each day of discharge is an additional violation
until approval has been secured. "
E. Noncompliant Effluent Individual Grab Sample
During the April 4, 1986 inspection, an effluent individual grab
sample was obtained and the analytical results are as follows :
1 . pH (standard units) 7 . 3
2 . Ortho-Phosphates (mg/1) 4 .01
*3 . Total Suspended Solids (mg/1) 320
4 . Ammonia-Nitrogen (mg/1) 2 . 75
*5 . Biochemical Oxygen Demand (mg/1) 85
6 . Nitrates (mg/1) 0 .13
7 . Nitrites (mg/1) 0 . 216
*Item l.a . , under "Other Requirements" states:
"Each pollutant concentration in a grab sample in excess
of the value shown for such pollutant in Column 2 of Table 1
constitutes a violation of the permit. "
Table 1
Pollutant Column 1 Column 2
BOD5 mg/1 35 65
Suspended Solids mg/1 35 65
F. Wastewater Treatment Plant Design Deficiencies
On August 19 , 1985, the District 4 Office notified the City of
Wylie by letter of design deficiencies that exist at the
wastewater treatment facilities . Since that date, many of
. City of Wylie
Permit No. WQ0010384-001
May 14 , 1986
Page 6
The same design deficiencies remain and are as follows:
(a) Oxidation Ditch
The Texas Administrative Code Chapter 317 . 4 (h) (1) (B) states,
"There shall be a minimum of two rotors per ditch, each having
the capability of supplying the required oxygenation capacity
with one rotor out of service. "
In order to consistently meet effluent permit requirements, the
City of Wylie wastewater treatment plant requires both mechanical
rotors to be functioning simultaneously.
(b) Final Clarifier
The Texas Administrative Code Chapter 317 . 4 (d) (5) states, "The
following design criteria for clarifiers are considered acceptable:
Final : Activated sludge - maximum surface loading at design flow
(gal/sq . /ft. /day) = 300" .
The City of Wylie wastewater treatment plant final clarifier
surface loading at design flow = 786 .6 gal/sq. /ft. /day.
(c) Drying Bed Capacity
The Texas Administrative Code 317 .12 Appendix D, "Required area
(sq.ft. /capita) for sludge drying beds with aerobic sludges -
Collin County = 1 .5 sq. ft. .
The 1984 population estimate for the City of Wylie = 1, 400
("Current Population 1984 Estimates" , North Central Texas
Council of Governments, May 1984) .
The square foot per capita sludge drying bed capacity at the City
of Wylie wastewater treatment plant = 0 . 5 sq. ft. /capita.
Since the August 19, 1985 District 4 letter, the only known
alterations made at the wastewater treatment plant is that a
tap was installed on the sludge return line in order to remove
additional solids from the system and dispose of solids at an
off-site area.
G. Semiannual Progress Reports
Item 8, under "Other Requirements" states, "Every six months
commencing January 1980, the permittee shall submit to the
department a report describing progress towards attainment
of the following monthly average effluent limitations :
Biochemical Oxygen Demand 10 mg/1
Total Suspended Solids 15 mg/1
The last such semiannual report received was January 24 , 1984 .

Dear Mayor Akin:
Re: Permit No. WQ0010384-001
On June 13, 1985, our field representative, Forrest B. John, accompanied by
Mr. W. W. Windham, City of Wylie Director of Public Works, conducted an inspec-
tion of a temporary lift station located on Douglas Street in the Oaks Develop-
ment. During the inspection, the following was noted:
1. An unauthorized discharge of raw wastewater was occurring due
to the lift station submersible pump being clogged.
2. There exists only one (1) submersible pump at the lift station.
3. There was no gate valve on the lift station discharge line.
In accordance with the "Design Criteria for Sewage Systems", Texas Department of
Water Resources Rules 156.17.02.001-.013, effective May 28, 1981, state:
.002(d)(e)(E) - "Whenever any pumping unit handles waste from two
or more residential housing units or from any public establishment,
dual grinder pump units shall be provided to assure continued service
in the event of equipment malfunction."
.003(d)(2) - "Valves: Full closing valves shall be installed on the
discharge piping to each pump and on the suction of all dry pit pumps.
A swing check valve with external lever shall be installed on the
discharge of each pump. Butterfly valves, tilting disc check valves,
or other valves with a pivoted disc in the flow line are not recom-
mended." •
In discussing the problems of the lift station, Mr. W. W. Windham reported to our
field representative that the lift station was temporary in nature and there would

be no new connections to the lift station. However, the Texas Department of
Health had never been notified of the lift station prior to construction.
Section .001(a)(3)(F) of the "Design Criteria for Sewage Systems" states:
"When changes or alterations are planned for existing systems,
notification to the Reviewing Authority shall be made and shall
include sufficient information to describe the significance of
such modifications. The Reviewing Authority will determine
whether engineering plans and specifications will be required
following this initial notification of the extent of the planned
modifications."
In addition, Item (4), under "Other Requirements" of Permit No. WQ0010384-001
states:
"The plans and specifications for the waste collection and treat-
ment works associated with the discharge authorized by this permit
must be approved pursuant to state law, and failure to secure
approval before commencing construction of such works or making
a discharge therefrom is a violation of this permit and each day
of discharge is an additional violation until approval has been
secured."
As you are aware, the discharge of wastewater, at the Oaks Development lift station,
was an unauthorized discharge and the city should take whatever action necessary
to prevent future unauthorized wastewater discharges. However, in the event that
such discharge should occur, such discharge must be reported in accordance with
Item (3), under "Special Conditions" of Permit No. WQ0010384-001.
Please advise this office in writing, within 35 days of the date of this letter,
of the steps taken to correct noted items (2) and (3) in accordance with all
provisions established in the "Design Criteria for Sewage Systems" and when the
plans and specifications for the lift station will be submitted for approval to
the Texas Department of Health (TDH). All corrective steps and TDH approval must
be accomplished within 90 calendar days of the date of this letter.
If you should have any questions, please contact Forrest B. John at 203 James
Collins Boulevard, Duncanville, Texas 75116; phone (214)298-6171.
