The hazardous waste management system--Environmental Protection Agency. Interim final amendments to interim final and final rules.

The Resource Conservation and Recovery Act (RCRA) requires that EPA set regulatory standards for all facilities which treat, store, or dispose of hazardous waste. In partial implementation of its requirement, on January 23, 1981, EPA set regulatory standards for incinerators that burn hazardous waste. These regulations were issued as "interim final," which means that, although they were issued in final form, the Agency invited public comment on them with a view to future amendment. Today, EPA is amending, on an interim final basis, certain of its regulations applicable to hazardous waste incineration facilities. Today's amendments include revisions to: the general standards for permitting hazardous waste incinerators (Part 264, Subpart O), published in the Federal Register on January 23, 1981; the interim status standards for hazardous waste incinerators (Part 265, Subpart O), revised on January 23, 1981; and the consolidated permit requirements for incinerators (Part 122), published on May 19, 1980 and January 23, 1981.U

Hazardous waste management system--Environmental Protection Agency. Notice of regulatory reform actions; request for comments.

In response to Executive Order 12291 and the President's Task Force on Regulatory Relief, the Environmental Protection Agency is reviewing and reassessing the hazardous waste regulations developed under the Resource Conservation and Recovery Act (RCRA). A variety of activities are underway that will simplify procedures and reduce paperwork, modify existing regulations to make them more workable and cost effective, and control new wastes and new processes. The purpose of this notice is to inform the public of these activities and invite comments on the general approaches being taken.

Consolidated permit regulations and hazardous waste management system: Environmental Protection Agency. Notice of issuance of regulation interpretation memorandum.

The Environmental Protection Agency (EPA) is issuing today a Regulation Interpretation Memorandum (RIM) which provides official interpretation of the issue of whether a generator who accumulates hazardous waste pursuant to 40 CFR 262.34, may qualify for interim status after November 19, 1980. This issue arose when the requirements for submitting a Part A permit application (one of the prerequisites to qualifying for interim status) were amended on November 19, 1980. The provisions interpreted today are part of the Consolidated Permit Regulations promulgated under Subtitle C of the Solid Waste Disposal Act, as amended by the Resource Conservation and Recovery Act, as amended (RCRA).

Municipal solid waste management through vermicomposting employing exotic and local species of earthworms.

A comparative study was conducted between exotic and local (epigeic--Eisenia fetida and anaecic--Lempito mauritii, respectively) species of earthworms for the evaluation of their efficacy in vermicomposting of municipal solid waste (MSW). Vermicomposting of MSW for 42 days resulted in significant difference between the two species in their performance measured as loss in total organic carbon, carbon-nitrogen ratio (C:N) and increase in total Kjeldahl nitrogen, electrical conductivity and total potassium and weight loss of MSW. The change in pH and increase in number of earthworms and cocoons and weight of earthworms were non-significant.

Hazardous waste management programs; Florida: authorization for interim authorization phase I--Environmental Protection Agency. Notice of final determination.

The State of Florida has applied for interim Authorization Phase I. EPA has reviewed Florida's application for Phase I and has determined that Florida's hazardous waste program is substantially equivalent to the Federal program covered by Phase I. The State of Florida is, hereby, granted Interim Authorization for Phase I to operate the State 's hazardous waste program, in lieu of the Federal program.

Themes for mushroom exploitation in the 21st century: Sustainability, waste management, and conservation.

Because many natural resources are limited, sustainability becomes an important concept in maintaining the human population, health, and environment. Mushrooms are a group of saprotrophic fungi. Mushroom cultivation is a direct utilization of their ecological role in the bioconversion of solid wastes generated from industry and agriculture into edible biomass, which could also be regarded as a functional food or as a source of drugs and pharmaceuticals. To make the mushroom cultivation an environmentally friendly industry, the basic biology of mushrooms and the cultivation technology must be researched and developed. This is very true for Lentinula edodes, Volvariella volvacea, and Ganoderma lucidum, which are commonly consumed in Asian communities but are now gaining popularity worldwide. Besides the conventional method, strain improvement can also be exploited by protoplast fusion and transformation. Biodiversity is the key contribution to the genetic resource for breeding programs to fulfill different consumer demands. The conservation of these mushrooms becomes essential and is in immediate need not only because of the massive habitat loss as a result of human inhabitation and deforestation, but also because of the introduced competition by a cultivar with the wild germ plasm. Spent mushroom compost, a bulky solid waste generated from the mushroom industry, however, can be exploited as a soil fertilizer and as a prospective bioremediating agent.
