Completing the Industrial Wastewater Permit Application - TCEQ e ...

f. If this is a new permit application for an existing facility, check “Yes.” Otherwise, check“No.”If yes, provide background discussion which explains the reason for pursuing anauthorization to dispose of wastewater (e.g., new process which generates wastewater,enforcement action, etc.).g. If the existing or planned treatment facility or disposal site is or will be located above theelevation of the 100-year frequency flood event, check “Yes.” Otherwise, check “No.” Listthe source of data you used to make your determination. Treatment units and disposal sitesmust be protected from inundation from a 100-year frequency flood event.If no, provide the elevation of the 100-year frequency flood plain and describe whatprotective measures are in use or planned to be used to prevent flooding of the treatmentfacility/disposal area. If applicable, provide the size of dikes or other protective structuresbeing utilized. Include a site map showing the location of the treatment plant/disposal areawithin the 100-year frequency flood level.h. For new or amendment permit applications, if any construction operations will result ina discharge of fill material into a water in the state, check “Yes.” Otherwise, check “No.”If yes, provide (if available) the U.S. Army Corps of Engineers (USACE) CWA Chapter 404Dredge and Fill Permit Number for purposes of tracking the 401 certification by the TCEQ.If no, provide the approximate date you plan to submit your application to the Corps.Note: It is the responsibility of the applicant to contact the USACE to obtain all necessaryauthorization, including a Federal CWA Chapter 404 Dredge and Fill permit, if necessary.The TCEQ is responsible for certifying that federal permits for the discharge of fill materialinto waters in the state are consistent with the state water quality standards. Thisinformation about the USACE 404 discharge permit is requested to ensure the mostefficient review of all actions by TCEQ on a wastewater discharge permit that also requiresa USACE permit.2. TREATMENT SYSTEMa. List any physical, chemical, or biological treatment process(es) that you use to treatwastewater authorized or to be authorized for disposal at your facility. This list should bespecific and include each unit in the treatment process and dimensions (e.g., dissolved airflotation, chemical precipitation, equalization, pH control, aeration, steam stripping,clarification, anaerobic lagoon). Please specify the associated outfall for each treatment unitand which wastewaters are chlorinated prior to discharge.b. Attach a flow schematic with a water balance showing each treatment unit (includingany lagoons, ponds, or impoundments) and all sources of wastewater flow into thetreatment plant and to each outfall/point of disposal. Indicate with a check mark that thishas been provided. This schematic should include all process wastewater, cooling water,domestic wastewater, and stormwater. The water balance must show average flows atintake, between units, treatment units, and discharge points. If a water balance cannot bedetermined (e.g., for certain mining activities), the applicant may provide instead apictorial description of the nature and amount of any sources of water and any collectionand treatment measures. (See Appendix 3 for an example of a water balance schematic.)10411_10055-inst (7/14/2014) Instructions for Completing the Industrial Wastewater Application Page 40 of 124
