Universal Citation: 30 TX Admin Code § 331.65
Current through Reg. 50, No. 13; March 28, 2025
(a) Applicability. Subsections (b) - (d) of this section apply to all Class I wells except for those Class I wells authorized to inject only nonhazardous desalination concentrate or nonhazardous drinking water treatment residuals.
(b) Pre-operation reports. For new wells, including wells converting to Class I status, the requirements are as follows.
(1) Completion report. Within 90 days after the completion or conversion of the well, the permittee shall submit a Completion Report to the executive director. The report must include a surveyor's plat showing the exact location and giving the latitude and longitude of the well. The report must also include a certification that a notation on the deed to the facility property or on some other instrument which is normally examined during title search has been made stating the surveyed location of the well, the well permit number, and its permitted waste streams. The permittee shall also include in the report the following, prepared and sealed by a licensed professional engineer or licensed professional geoscientist with current registration under the Texas Engineering Practice Act or Texas Geoscience Practice Act:
(A) actual as-built drilling and completion data on the well;
(B) all logging and testing data on the well;
(C) a demonstration of mechanical integrity;
(D) anticipated maximum pressure and flow rate at which the permittee will operate;
(E) results of the injection zone and confining zone testing program as required in §
331.62 of this title (relating to Construction Standards) and this subsection;
(F) adjusted formation pressure increase calculations, fluid front calculations and updated cross-sections of the confining and injection zones, based on the data obtained during construction and testing;
(G) the actual injection procedure;
(H) the compatibility of injected wastes with fluids in the injection zone and minerals in both the injection zone and the confining zone and materials used to construct the well;
(I) the calculated area of review and cone of influence based on data obtained during logging and testing of the well and the formation, and where necessary, revisions to the information submitted under §
331.121 of this title (relating to Class I Wells);
(J) the status of corrective action required for defective wells in the area of review;
(K) a Well Data Report on forms provided by the executive director;
(L) compliance with the casing and cementing performance standard in §
331.62(5) of this title; and
(M) compliance with the cementing requirements in §
331.62(6) of this title.
(2) Local authorities. The permittee shall provide written notice to the executive director, in a manner specified by the executive director, that a copy of the permit has been properly filed with the health and pollution control authorities of the county, city, and town where the well is located.
(3) Start-up date and time. The permittee shall notify the executive director in writing of the anticipated well start-up date. Compliance with all pre-operation terms of the permit must occur prior to beginning injection operations. The permittee shall notify the executive director at least 24 hours prior to beginning drilling operations.
(4) Approval of construction and completion. Prior to beginning operations, the permittee must obtain written approval from the executive director, according to §
331.45 of this title (relating to Executive Director Approval of Construction and Completion).
(c) Operating reports.
(1) Injection operation quarterly report. For non-commercial facilities only, within 20 days after the last day of the months of March, June, September, and December, the permittee shall submit to the executive director a quarterly report of injection operation on forms supplied by the executive director. These forms will comply with the reporting requirements of 40 Code of Federal Regulations (CFR) §146.69(a). The executive director may require more frequent reporting.
(2) Injection operation monthly report. Commercial facilities shall meet the following requirements.
(A) The permittee shall submit within 30 days after the last day of each month a report to the commission including the following information for wastes received and injected during the month:
(i) names and locations of the companies and plants generating the wastes;
(ii) chemical and physical characteristics and volume of waste received from each company including pH;
(iii) names of companies transporting the wastes; and
(iv) a log of injection operations for each injection episode including but not limited to time of injection, injection rate, injection pressures, injection fluid volume, injection fluid pH, and injection fluid density.
(B) The permittee shall submit to the commission within 20 days of the last day of each month a report of injection operations on forms provided by the commission. These forms shall comply with the reporting requirements of 40 CFR §146.69(a). The executive director may require more frequent reporting.
(3) Injection zone annual report. For all facilities, the permittee shall submit annually with the December report of injection operation an updated graphic or other acceptable report of the pressure effects of the well upon its injection zone as required by §
331.64(h) of this title (relating to Monitoring and Testing Requirements). To the extent this information is reasonably available, the report must also include:
(A) locations of newly constructed or newly discovered wells that penetrate the confining and/or injection zone within the area of review if those wells were not included in the technical report accompanying the permit application or in later reports;
(B) a tabulation of data as required by §
331.121(a)(2)(B) of this title for wells within the area of review that penetrate the injection zone or confining zone;
(C) the condition of the wells identified in subparagraph (A) of this paragraph and their effect on the injection activities;
(D) the protocol followed to identify, locate, and ascertain the condition of the wells identified in subparagraph (A) of this paragraph;
(E) a corrective action plan for wells not adequately constructed, completed, or plugged; and
(F) for non-commercial facilities only, a current injection fluid analysis.
(4) Mechanical integrity and other reports. The permittee shall submit within 30 days after test completion, a report including both data and interpretation on the results of:
(A) periodic tests of mechanical integrity; and
(B) any other test of the injection well or injection zone if required by the executive director.
(5) Emergency report of leak or other failure. The permittee shall notify the Underground Injection Control (UIC) Unit of the Austin office of the commission within 24 hours of any significant change in monitoring parameters or of any other observations which could reasonably be attributed to a leak or other failure of the well equipment or injection zone integrity.
(d) Workover reports. Within 30 days after the completion of the workover, a report shall be filed with the executive director including the reason for well workover and the details of all work performed.
(e) Class I Wells authorized to inject only nonhazardous desalination concentrate or nonhazardous drinking water treatment residuals shall comply with the following reporting requirements:
(1) Completion Reports. A new injection well may not commence injection until construction is complete, and
(A) The permittee has submitted notice of completion of construction to the executive director; and
(B) The executive director has inspected or otherwise reviewed the new injection well and finds it is in compliance with the conditions of the permit; or
(C) The permittee has not received notice from the executive director of his intent to inspect or otherwise review the new injection well within 13 days of the date of the notice in paragraph (1)(A) of this subsection, in which case prior inspection or review is waived and the permittee may commence injection. The executive director shall include in his notice a reasonable time period in which he shall inspect the well.
(2) Operating Reports. The owner or operator shall submit reports to the executive director as follows:
(A) Quarterly reports on:
(i) The physical, chemical, and other relevant characteristics of the injection fluids;
(ii) Monthly average, maximum, and minimum values for injection pressure, flow rate and volume, and annular pressure;
(iii) The results from ground-water monitoring wells prescribed in paragraph §
331.64(k)(10) of this title (relating to Monitoring and Testing Requirements);
(iv) The results of any test of the injection well conducted by the owner or operator during the reported quarter if required by the executive director; and
