The town clearly understands that there are technical criteria, legal requirements, and administrative procedures and duties associated with regulating on-site sewage facilities, and will fully enforce chapter 366 of the Texas Health and Safety Code (H&SC) and chapters 7 and 37 of the Texas Water Code (TWC), and associated rules referenced in section 13.05.004 of this article.
(Ordinance 2009-2-10B adopted 2/10/09)
The rules, title 30 Texas Administrative Code (TAC) sections 285.1–285.91 and TAC 30, attached to Ordinance 2009-2-10B, promulgated by the Texas Commission on Environmental Quality for on-site sewage facilities are hereby adopted, and all officials and employees of the town having duties under said rules are authorized to perform such duties as are required of them under said rules.
(Ordinance 2009-2-10B adopted 2/10/09)
The rules, 30 TAC chapters 30 and 285 and all future amendments and revisions thereto are incorporated by reference and are thus made a part of these rules. A copy of the current rules is attached to these rules as appendix I of Ordinance 2009-2-10B on file in the office of the town secretary.
(Ordinance 2009-2-10B adopted 2/10/09)
The town wishing to adopt more stringent rules for its on-site sewage facility ordinance understands that the more stringent conflicting local rule shall take precedence over the corresponding Texas Commission on Environmental Quality requirement. Listed below are the more stringent rules adopted by the town:
(1) 
An OSSF shall not be permitted on less than one acre, except where a residential lot of one-half acre or more has already been platted within an existing subdivision.
(2) 
Exception: The town engineer may approve construction of on-site sewage facilities (OSSF) on residential lots of more than one-half acre but less than one acre, where the lot is not platted within an existing subdivision, is not contiguous to undeveloped property that may reasonably be conjoined or has the same property owner, and is not served by municipal wastewater service.
(3) 
A permit shall be required for all OSSF regardless of acreage.
(4) 
The owner or person who has legal responsibility of an existing OSSF shall have the system inspected before any sales and/or transfers of ownership.
(5) 
Grease trap sizing, if applicable, shall be done using the EPA method and the International Plumbing Code method; the larger of the two resulting tank sizes shall be used.
(6) 
Calculations for hydraulic and organic load for both normal and peak flows on all commercial systems shall be provided showing that both organic and hydraulic overloading of the treatment and/or disposal method is prevented.
(7) 
All planning material must be prepared by a professional engineer or registered sanitarian authorized to practice in the state.
(8) 
Aerobic plants tested under NSF standard 40 shall be sized for residential units based on an assumed hydraulic load of 150 gallons per day per bedroom.
(9) 
New anaerobic systems shall not be permitted.
(10) 
The allowable timeframe for a maintenance company to respond to a complaint from the property owner or electronic notification shall be no longer than 48 hours.

(A) 
Residential.
Three (3) inspections per year;
(B) 
Residential electronically monitored.
Two (2) inspections per year;
(C) 
Commercial.
Twelve (12) inspections per year. (Requests for decreased frequency for commercial systems will be considered on a case-by-case basis.)
(12) 
All new commercial systems requiring on-going maintenance by these rules shall be electronically monitored. Other systems may be electronically monitored to reduce the number of required maintenance visits.
(13) 
Electronic monitoring must be continuously maintained.
(14) 
For structures with more than one sewer stub out or other similar instances, all sewer lines shall have a common connection prior to entering the main tank battery unless the tank battery is designed with more than one entrance.

All installers and their apprentices shall maintain copies of approved plans, contracts, manifests, well data, and component specifications required and specified by the approved plans on the job site and make available to the inspector until all required inspections are completed.
(16) 
Owners of OSSF requiring maintenance under these rules must acquire and maintain a maintenance, testing, and reporting contract with a licensed maintenance company; homeowner maintenance shall be prohibited.
(17) 
All components that need to be replaced on an aerobic treatment system must be replaced by a licensed installer and must be component compatible.

The OSSF inspector of the town, must be certified by the Texas Commission on Environmental Quality before assuming the duties and responsibilities.
(Ordinance 2009-2-10B adopted 2/10/09)
Persons aggrieved by an action or decision of the designated representative may appeal such action or decision to the town council.
(Ordinance 2009-2-10B adopted 2/10/09)
