DEFINITIONS AND STANDARD PERMIT CONDITIONS
As required by Title 30 Texas Administrative Code (TAC) Chapter 305, certain regulations appear as standard conditions in waste
discharge permits. 30 TAC § § 305.121 - 305.129 (relating to Permit Characteristics and Conditions) as promulgated under the
Texas Water Code 5.103 and 5.105, and the Texas Health and Safety Code 361.017. and 361.024(a), .establish the
characteristics and standards for waste discharge permits, including sewage sludge, and those sections of 40 Code of Federal
Regulations (CFR) Part 122 adopted by reference by the Commission. The- following text includes these conditions and
incorporates them into this permit. All definitions in Section 26.001 of the Texas-Water Code and 30 TAC .Chapter 305 shall
apply to this permit and are incorporated by reference. Some specific defmitions of words or phrases used in this permit are as
follows:
1. Flow Measurements
a. Annual average flow -the arithmetic average of all daily flow determinations taken within the preceding 12 consecutive
calendar months. The annual average flow determination shall consist of daily flow volume determinations made by a
totalizing meter, charted on a chart recorder and limited to major domestic wastewater discharge facilities with a 1
million$a11o~Pe-,Ada-Y-or-g3'eater-per~i#t~d~low.
b. Daily average flow -the arithmetic average of all determinations of the daily flow within a period of one calendar month.
The daily average flow determination shall consist of determinations made on at least four separate days. If instantaneous
measurements are used to determine the daily flow, the determination shall be the arithmetic average of all instantaneous
measurements taken during that month. Daily average flow determination for intermittent discharges shall consist of a
minimum of three flow determinations on days of discharge. .
c. Daily maximum flow -the highest total flow for any 24-hour period in a calendar month.
d. Instantaneous flow -the measured flow during the minimum time required to interpret the flow measuring device.
e. 2-hour peak flow (domestic wastewater treatment plants) -the maximum flow sustained for atwo-hour period during
the period of daily discharge: The.average of multiple measurements of instantaneous. maximum flowwithin atwo-hour
period maybe used to calculate the 2-hour peak flow.
f. Maximum2-hourpeakflow(domesticwastewatertreatmentplants)-thehighest2-hourpeakflowforany24-hourperiod
in a calender month.
2. Concentration Measurements
a. Daily average concentration -the arithmetic average of all effluent samples, composite or grab as required by this permit,
within a period of one calendar month, consisting of at least four separate representative measurements.
i. For domestic wastewater treatment plants -When four samples are not available in a calendar month, the arithmetic
average (weighted by flow) of all values in the previous four consecutive month period consisting of at least four
measurements shall be utilized as the daily average concentration.
ii. For all other wastewater treatment plants -When four samples are not available in a calender month, the arithmetic
average (weighted by flow) of all values taken during the month shall be utilized as the daily average concentration.
b. 7-day average concentration - the arithmetic average of all effluent samples, composite or grab as required by this permit,
within a period of one calendar week, Sunday through Saturday.
c. Daily maximum concentration -the maximum concentration measured on a single day, by the sample type specified in
the permit, within a period of one calender month.
d. Daily discharge -the discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably
represents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the
"daily discharge" is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants with
limitations expressed in other units of measurement, the "daily discharge" is calculated as-the average measurement of
the pollutant over the sampling day.
The "daily discharge" determination of concentration made using a composite sample shall be the concentration of the
composite sample. When grab samples are used, the "daily discharge" determination of concentration shall be the
arithmetic average (weighted by flow value) of all samples collected during that day.

c. Permits for domestic wastewater treatment plants are granted subject to the policy of the Commission to encourage the
development ofarea-wide waste collection, treatment and disposal systems. The Commission reserves the rightto amend
any domestic wastewater permit in accordance with applicable procedural requirements to require the system covered
by this permit to be integrated into an area-wide system, should such be developed; to require the delivery of the wastes
authorized to be collected in, treated by or discharged from said system, to such area-wide system; or to amend this
permit in angother particular to effectuate the Commission's policy. Such amendments may be made when the changes
required are advisable for water quality control purposes and are feasible on the basis of waste treatment technology,
engineering, financial, and related considerations existing at the time the changes are required, exclusive of the loss of
investment in or revenues from any then existing or proposed waste collection, treatment or disposal system.

All sewage sludge that is applied to agricultural land, forest, a public contact site, or a reclamation site shall be treated by one
of the following methods to ensure that the sludge meets either the Class A or Class B pathogen requirements.
a. Six alternatives are available to demonstrate compliance with Class A sewage sludge. The first 4 options require _
either the density of fecal coliform in the sewage sludge be less than 1000 Most Probable Number (MPN) per gram
of total solids (dry weight basis), or the density of Salmonella sp. bacteria in the sewage sludge be .less than three
•MPNper four grams of total solids (dry weight basis) at the time the sewage sludge is used or disposed. Below are
the additional requirements necessary to meet the definition of a Class A sludge.
Alternative 1 -The temperature of the sewage sludge that is used or disposed shall be maintained at or above a
specific value for a period of time. See 30 TAC Section 312.82(a)(Z)(A).fnr specific information.
Alternative 2 -The pH of the sewage sludge that is used or disposed shall be raised to above 12 std. units and shall
remain above 12 std. units for 72 hours.
The temperature of the sewage sludge shall be above 52 degrees Celsius for 12 hours or longer during the period
that the pH of the sewage sludge is above 12 std. units.
At the end of the 72-hour period during which the pH of the sewage~sludge is above 12 std. units, the sewage sludge
shall be air dried to achieve a percent solids in the sewage sludge greater than 50 percent.
Alternative 3 -The sewage sludge shall be analyzed for enteric viruses prior to pathogen treatment. The limit for
enteric viruses is less than one Plaque-forming Unit per four grams of total solids (dry weight basis) either before
or following pathogen treatment. See 30 TAC Section 312.82(a)(2)(C)(i-iii) for specific information. The sewage
sludge shall be analyzed for viable hehninth ova prior to pathogen treatment. The limit for viable helminth ova is
less than one per four grams of total solids (dry weight basis) either before or following pathogen treatrnent. See
30 TAC Section 312.82(a)(2)(C)(iv-vi) for specific information.
Alternative 4 -The density of enteric viruses in the sewage sludge shall be less than one Plaque-forming Unit per
four grams of total solids. (dry weight basis) at the time the sewage sludge is used or disposed. The density of viable
hehninth ova in the sewage sludge shall be less than one per four grams of total solids (dry weight basis) at the time
the sewage sludge is used or disposed.
Alternative 5 (PFRP) -Sewage sludge that is used or disposed of shall be treated in one of the processes to Further
Reduce Pathogens (PFRP) described in40 CFRPart 503, Appendix B. PFRP include composting, heat drying, heat
treatment, and thermophilic aerobic digestion.
Alternative 6 (PFRP Equivalent) -Sewage sludge that is used or disposed of shall be treated in a process that has
been approved by the U. S. Environmental Protection Agency as being equivalent to those in Alternative 5.
