Hazardous Waste Technical Guidance Document: Determining the 
Integrity of Concrete Sumps (EPA/530-R-93-005)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Publication of technical guidance document.

-----------------------------------------------------------------------

SUMMARY: EPA announces the publication of Technical Guidance Document: 
Determining the Integrity of Concrete Sumps (EPA/530-R-93-005) and the 
availability of copies from the National Technical Information Service. 
This TGD was developed by EPA's Risk Reduction Engineering Lab 
(Cincinnati) in cooperation with Office of Solid Waste to provide 
information on conducting integrity assessments of sumps (a type of 
tank) in which hazardous wastes are managed.
    The guidance explains how to assess the structural integrity of a 
hazardous waste sump that is made of concrete. First, mechanisms of 
concrete structural failure are discussed to provide a basis for 
conducting investigations. The TGD explains the steps for basic and 
secondary investigations, including methods for concrete inspection and 
sump leak testing. As part of the basic investigation, the guidance 
describes an approach for static head leak testing of water-filled 
sumps. Lastly, methods for repairing concrete and information on 
coatings are presented.
    Even though the guidance offers very helpful information for most 
sumps, it does not cover all the situations that the facility owners/
operators, permit writers, and inspectors may face in assessing the 
integrity of concrete sumps. This is especially true of very large 
sumps--the TGD may not provide methods that can be effectively applied 
to them. Additional methods may have been developed since the TGD was 
prepared.

Guidance Purchase

    The TGD is available for purchase from the National Technical 
Information Service (NTIS). The NTIS order number is PB93-154631. EPA 
cannot provide copies. Call NTIS at (703) 487-4650 from 8:30 a.m. to 
5:30 p.m. Eastern time to get an order form.

Comments

    Any comments on the TGD should be sent to: Sump Guidance, Office of 
Solid Waste, 5304, U.S. Environmental Protection Agency, 401 M Street, 
SW., Washington, DC 20460.
    Please identify the document fully as: Technical Guidance Document: 
Determining the Integrity of Concrete Sumps (EPA/530-R-93-005).
