IOMs describe new policies, changes to existing policies or guidance, new legislation, new human health risk assessment information, etc.

  • IOM-090606, Chapter 334 Closure Criteria for Domestic Irrigation Wells (Sept. 6, 2006). Addresses the allowable levels of groundwater contamination that can remain in place in domestic irrigation wells at Chapter 334 leaking petroleum storage tank (LPST) sites at the time of site closure.
  • IOM-073103, Sample Handling and Preservation Procedures; Collection Procedures for Groundwater Samples (July 31, 2003). Reiterates standard industry procedures for proper collection, handling and custody of environmental samples, which apply to all samples collected under any TCEQ Remediation Division program (e.g., PST Program, Corrective Action, Voluntary Cleanup Program). Outlines a new custody procedure that must be followed when samples will not be received by the laboratory within two (2) days of sample collection. Brief discussion of previously issued TCEQ guidance ("Consistency Memorandum", July 23, 1998) on low-flow groundwater collection and filtering.
  • IOM-071703, Process for Expedited Closure Evaluation for Priority 4.1 Petroleum Hydrocarbon LPST Sites (July 17, 2003). Describes how and under what conditions, LPST sites that are considered low-risk can be brought to closure quickly and appropriately.
  • IOM-111201, LPST Program Corrective Action Deadlines Effective September 1, 2001 (November 12, 2001). HB 2912Exit TCEQ (the TCEQ "Sunset" bill) and HB 2687Exit TCEQ, both enacted by the 77th Texas Regular Legislative Session of 2001, impose new corrective action, annual reporting, and reimbursement deadlines on certain LPST sites and also extend the life of the Petroleum Storage Tank Remediation (PSTR) fund through August 31, 2006. The new statutory deadlines apply to all LPST sites where the release was reported to the agency on or before December 22, 1998, whether corrective action costs are eligible for reimbursement or not.
    • A mass mailout discussing the new legislation and new deadlines was prepared and mailed to over 5000 responsible parties (RPs) November 12, 2001. Included in the mailout package was a cover letter, guidance document (includes a summary table of applicable PST Program guidance documents and forms), and form. Frequently Asked Questions (FAQs) are also available.
    • The form in the mailout packet is to be filled out only by persons believing that they received the mailout in error, either because they are not the RP, or there is a different point of contact for the RP. RPs that believe they are financially unable to complete the necessary corrective actions at their sites, are advised to contact the PST Responsible Party Remediation section (e-mail or phone 512-239-2200) to request a State-Lead packet.
  • IOM-051801, Guidelines for Sampling Domestic Water Wells for Petroleum Storage Tank Contaminants (05/18/2001). Provides general guidelines for collecting representative water samples from domestic water wells.
  • IOM-011001, Standard Operating Procedure for Evaluation of Costs of Sampling & Analysis of Groundwater Samples for Monitor Wells with Water Levels Above the Top of the Wellscreen (01/10/2001). Explains reimbursement eligibility for groundwater samples collected from monitoring wells screened above and below the top of the water table.
  • IOM-110199, Guidance for Leaking Petroleum Storage Tank (LPST) Sites Located on State Designated Major/Minor Aquifers or Local Water Supply (11/1/1999). Applies to sites where the impact has affected a known local/regional water supply or State Designated Major/Minor Aquifer. Criteria replaces applicable portions of Items 3 and 4 of the March 6, 1997 RG-36 Clarification IOM.
  • IOM-022398, Preapproval Costs for Groundwater Monitoring of RNA Parameters (2/23/1998). Future groundwater monitoring workplans should clearly state the indicator data. Workplans should also clearly identify which data, if any, will be obtained through laboratory analysis rather than field methods. Outlines allowable costs for this activity. Available in the following formats: WordPerfect 6.1 and PDF.
  • IOM-081297, Protective Concentrations in Groundwater for Construction Worker Exposure(8/12/1997). This IOM outlines the process and criteria regarding construction worker exposure to groundwater and should be used to determine appropriate actions that should be taken at LPST sites to address the construction worker/groundwater exposure issue. This IOM includes the following PDF files:
    • August 12, 1997 IOM on Adjustments to March 6, 1997, Protective Concentrations in Groundwater.... (approx. 132 kb)
    • Attachment 2 - Chemical/Physical Properties Table (approx. 31 kb)
    • References (approx. 16 kb) - The reference file goes with the Attachment II Chemical/Physical Properties Table.
  • IOM-042997, Interim Guidance1: Monitoring Natural Attenuation for Verification of Groundwater Plume Stability (4/29/1997). Based on a paper by McAllister, P.M., and Chiang, C.Y., 1994, A Practical Approach to Evaluating Natural Attenuation of Contaminants in Ground Water, in Ground Water Monitoring and Remediation, V.14, pp. 161-173.
  • IOM-030697, Clarifications and Amendments for Implementation of RG-36 (3/6/1997). Modifies RG-36 (Risk-Based Corrective Action for Leaking Storage Tank Sites) to clarify when to conduct a Plan B risk assessment, and discusses exposure pathways and use of the exit criteria (see February 10, 1997 IOMs). Several changes have also been made to exposure equations and toxicity data.
  • IOM-021097. The following two IOMs were issued on 2/10/97: Guidance for Judging the Adequacy of Contaminant Delineation for Purposes of Determining if Further Corrective Action is Needed and Process for Closure Evaluation of Petroleum Hydrocarbon LPST Sites Exceeding Target Concentrations. These are known collectively as the Exit Criteria. They can be downloaded together in a packet containing the IOMs, a cover letter, and frequently asked questions (FAQs). A second PDF file contains errata.
