|(a) Type V mobile liquid waste processing unit demonstration of viability. (1) The owner or operator shall not initiate operation of each unit until a pre-operation inspection of each mobile unit has been conducted and the executive director gives written authorization to accept waste. The owner or operator shall demonstrate under field conditions that the process works. The demonstration shall be conducted under the supervision of experienced executive director staff and when appropriate, with local government staff. The viability demonstration shall be made by processing three traps in a single day representative of the traps normally serviced. The traps must have been in operation and not have been serviced for at least 30 days prior to the demonstration. The volume of material to be processed before unloading must be consistent with manufacturer's performance specifications and the operating plan, particularly as to the expected ratios between gross volumes processed and amounts discharged following processing. Multiple grab samples of effluent taken from the discharge outlet of the mobile processing unit must be tested for fats, oils, greases, and pH and be designed and operated to meet the effluent limits imposed by its treatment facility permitted under Texas Water Code, Chapter 26, Texas Pollutant Discharge Elimination System, or the liquid effluent limits specified in §330.207(h) of this title (relating to Contaminated Water Management) if the discharge points do not require compliance with locally set limits. (2) Waste solids (sludges) produced by the mobile processing unit must be disposed of in a solid waste disposal facility regulated by the State of Texas or other location approved by the executive director. Solids should be dewatered to the point that they pass the United States Environmental Protection Agency (EPA) paint filter test, EPA Test Method 9095, or they should be taken to an authorized facility to be dewatered prior to landfilling. (3) The owner or operator shall remain responsible for making corrections or changes that are necessary to meet requirements prior to operating the mobile unit. (b) Type VI demonstration projects for liquid waste processing facilities. The operation of the facility shall not begin until a pre-opening inspection has been conducted and written authorization to accept waste has been given by the executive director.
