A task was undertaken to develop a method for analyzing industrial user responses to alternative rate designs. The method described considers the fuel switching and conservation responses of industrial users and the impact to a hypothetical utility regarding revenue stability, annual gas demand, and seasonal fluctuations. Twenty-seven hypothetical industrial plant types have been specified. For each combustor in the plant, the fuel consumption by season, initial fuel type, fuel switching costs, conservation costs, and amount of fuel conservable is provided. The decision making takes place at the plant level and is aggregated to determine the impact to the utility. Section 2 discusses the factors affecting an industrial user's response to alternative rate designs. Section 3 describes the methodology, includes an overview of the model and an example industrial user's response to a set of fuel prices. The data describing the 27 hypothetical firms is in an appendix.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Mark White, regarding a legal question submitted for clarification; Whether an automobile must be inspected before it can be registered.

A geotoxicity hazard index was developed for radioactive wastes buried in geologic media. Parameters are: toxicity, persistance, availability, and correction for progeny buildup. (DLC)

Numerical modeling of the transient cooling of a magmatic intrusion is described in a geothermal reservoir that results from conduction and convection, considering the effects of overlying cap rock and differing horizontal and vertical permeabilities of the reservoir. These results are compared with data from Salton Sea Geothermal Field (SSGF). Multiple layers of convection cells are observed when horizontal permeability is much larger than vertical permeability. The sharp drop-off of surface heat flow experimentally observed at SSGF is consistent with the numerical results. The age of the intrusive body at SSGF is estimated to be between 6000 and 20,000 years.
