Surface water discharges from onshore stripper wells.

Description: Under current US Environmental Protection Agency (EPA) rules, small onshore oil producers are allowed to discharge produced water to surface waters with approval from state agencies; but small onshore gas producers, however, are prohibited from discharging produced water to surface waters. The purpose of this report is to identify those states that allow surface water discharges from small onshore oil operations and to summarize the types of permitting controls they use. It is intended that the findings of this report will serve as a rationale to encourage the EPA to revise its rules and to remove the prohibition on surface water discharges from small gas operations.

Screening of Potential Remediation Methods for the 200-ZP-1 Operable Unit at the Hanford Site

Description: A screening-level evaluation of potential remediation methods for application to the contaminants of concern (COC) in the 200-ZP-1 Operable Unit at the Hanford Site was conducted based on the methods outlined in the Guidance for Conducting Remedial Investigations and Feasibility Studies under CERCLA Interim Final. The scope of this screening was to identify the most promising remediation methods for use in the more detailed analysis of remediation alternatives that will be conducted as part of the full feasibility study. The screening evaluation was conducted for the primary COC (potential major risk drivers). COC with similar properties were grouped for the screening evaluation. The screening evaluation was conducted in two primary steps. The initial screening step evaluated potential remediation methods based on whether they can be effectively applied within the environmental setting of the 200-ZP-1 Operable Unit for the specified contaminants. In the second step, potential remediation methods were screened using scoping calculations to estimate the scale of infrastructure, overall quantities of reagents, and conceptual approach for applying the method for each defined grouping of COC. Based on these estimates, each method was screened with respect to effectiveness, implementability, and relative cost categories of the CERCLA feasibility study screening process defined in EPA guidance.

How Does Your Data Center Measure Up? Energy Efficiency Metrics and Benchmarks for Data Center Infrastructure Systems

Description: Data centers are among the most energy intensive types of facilities, and they are growing dramatically in terms of size and intensity [EPA 2007]. As a result, in the last few years there has been increasing interest from stakeholders - ranging from data center managers to policy makers - to improve the energy efficiency of data centers, and there are several industry and government organizations that have developed tools, guidelines, and training programs. There are many opportunities to reduce energy use in data centers and benchmarking studies reveal a wide range of efficiency practices. Data center operators may not be aware of how efficient their facility may be relative to their peers, even for the same levels of service. Benchmarking is an effective way to compare one facility to another, and also to track the performance of a given facility over time. Toward that end, this article presents the key metrics that facility managers can use to assess, track, and manage the efficiency of the infrastructure systems in data centers, and thereby identify potential efficiency actions. Most of the benchmarking data presented in this article are drawn from the data center benchmarking database at Lawrence Berkeley National Laboratory (LBNL). The database was developed from studies commissioned by the California Energy Commission, Pacific Gas and Electric Co., the U.S. Department of Energy and the New York State Energy Research and Development Authority.

Analysis of 2011 Meteorological Data from the Knolls Atomic Power Laboratory and Kesselring Site Operations Facilities

Description: Both the Knolls Atomic Power Laboratory (KAPL) in Schenectady, NY and the Kesselring Site Operations (KSO) facility near Ballston Spa, NY are required to estimate the effects of hypothetical emissions of radiological material from their respective facilities by the US Environmental Protection Agency (EPA), which regulates these facilities. An atmospheric dispersion model known as CAP88, which was developed and approved by the EPA for such purposes, is used by KAPL and KSO to meet this requirement. CAP88 calculations over a given time period are based on statistical data on the meteorological conditions for that period. Both KAPL and KSO have on-site meteorological towers which take atmospheric measurements at a frequency ideal for EPA regulatory model input. However, an independent analysis and processing of the meteorological data from each tower is required to derive a data set appropriate for use in the CAP88 model. The National Atmospheric Release Advisory Center (NARAC) was contracted by KAPL to process the on-site data for the calendar year 2011. The purpose of this document is to: (1) summarize the procedures used in the preparation/analysis of the 2011 meteorological data; and (2) document adherence of these procedures to the guidance set forth in 'Meteorological Monitoring Guidance for Regulatory Modeling Applications', EPA document - EPA-454/R-99-005 (EPA-454). This document outlines the steps in analyzing and processing meteorological data from the Knolls Atomic Power Laboratory and Kesselring Site Operations facilities into a format that is compatible with the steady state dispersion model CAP88. This process is based on guidance from the EPA regarding the preparation of meteorological data for use in regulatory dispersion models. The analysis steps outlined in this document can be easily adapted to process data sets covering time period other than one year. The procedures will need to be modified should the guidance in EPA-454 be ...

Memo to Skip Laitner of EPA: initial comments on 'The internetbegins with coal'

Description: This memo explores the assumptions in Mark P. Mills' report titled 'The Internet Begins with Coal' that relate to current electricity use 'associated with the Internet'. We find that Mills has significantly overestimated electricity use, in some cases by more than an order of magnitude. We adjust his estimates to reflect measured data and more accurate assumptions, which reduces Mills' overall estimate of total Internet-related electricity use by about a factor of eight.

RCRA corrective action determination of no further action

Description: On July 27, 1990, the U.S. Environmental Protection Agency (EPA) proposed a regulatory framework (55 FR 30798) for responding to releases of hazardous waste and hazardous constituents from solid waste management units (SWMUs) at facilities seeking permits or permitted under the Resource Conservation and Recovery Act (RCRA). The proposed rule, `Corrective Action for Solid Waste Management Units at Hazardous Waste Facilities`, would create a new Subpart S under the 40 CFR 264 regulations, and outlines requirements for conducting RCRA Facility Investigations, evaluating potential remedies, and selecting and implementing remedies (i.e., corrective measures) at RCRA facilities. EPA anticipates instances where releases or suspected releases of hazardous wastes or constituents from SWMUs identified in a RCRA Facility Assessment, and subsequently addressed as part of required RCRA Facility Investigations, will be found to be non-existent or non-threatening to human health or the environment. Such releases may require no further action. For such situations, EPA proposed a mechanism for making a determination that no further corrective action is needed. This mechanism is known as a Determination of No Further Action (DNFA) (55 FR 30875). This information Brief describes what a DNFA is and discusses the mechanism for making a DNFA. This is one of a series of Information Briefs on RCRA corrective action.

Three Dimensional, Integrated Characterization and Archival System for Remote Facility Contaminant Characterization

Description: The largest problem facing the Department of Energy's Office of Environmental Management (EM) is the cleanup of the Cold War legacy nuclear production plants that were built and operated from the mid-forties through the late eighties. EM is now responsible for the remediation of no less than 353 projects at 53 sites across the country at, an estimated cost of $147 billion over the next 72 years. One of the keys to accomplishing a thorough cleanup of any site is a rigorous but quick contaminant characterization capability. If the contaminants present in a facility can be mapped accurately, the cleanup can proceed with surgical precision, using appropriate techniques for each contaminant type and location. The three dimensional, integrated characterization and archival system (3D-ICAS) was developed for the purpose of rapid, field level identification, mapping, and archiving of contaminant data. The system consists of three subsystems, an integrated work and operating station, a 3-D coherent laser radar, and a contaminant analysis unit. Target contaminants that can be identified include chemical (currently organic only), radiological, and base materials (asbestos). In operation, two steps are required. First, the remotely operable 3-D laser radar maps an area of interest in the spatial domain. Second, the remotely operable contaminant analysis unit maps the area of interest in the chemical, radiological, and base material domains. The resultant information is formatted for display and archived using an integrated workstation. A 3-D model of the merged spatial and contaminant domains cart be displayed along with a color-coded contaminant tag at each analysis point. In addition, all of the supporting detailed data are archived for subsequent QC checks. The 3D-ICAS system is capable of performing all contaminant characterization in a dwell time of 6 seconds. The radiological and chemical sensors operate at US Environmental Protection Agency regulatory levels. Base ...

Regulatory policy issues and the Clean Air Act: An interim report on the state implementation workshops

Description: The National Regulatory Research Institute (NRRI), with funding from the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE), conducted two workshops on state public utility commission implementation of the Clean Air Act Amendments of 1990 (CAAA). The first workshop was held in Charlotte, North Carolina for southern and eastern states in April 1992 and the second was held in St. Louis, Missouri for Midwestern states in May. The workshops had four objectives: (1) discuss key issues and concerns on CAAA implementation, (2) encourage a discussion among states on issues of common interest, (3) attempt to reach consensus, where possible, on some key issues, and (4) provide the workshop participants with information and materials to assist in developing rules, orders, and procedures in their state. Of primary interest from the federal perspective was for workshop participants to return to their states with additional background and understanding of how state commission actions may affect implementation of the CAAA and enable them to provide guidance to their jurisdictional utilities. It was hoped this would reduce some of the uncertainty utilities face and assist in the development of an efficient allowance market. The basic format of the workshops was that invited speakers made presentations on specific issues. {open_quotes}Primary participants{close_quotes} from each state and other workshop attendees then discussed the issues raised by the speakers and other related concerns. The primary participants were state commissioners, commission staff, representatives from state consumer advocate organizations, EPA, DOE, and the Federal Energy Regulatory Commission (FERC). Other attendees were utility representatives, consultants, and other interested parties. All participants were given a workbook with excerpts from an NRRI report on CAAA implementation and papers or outlines from speakers.

Pollution Prevention Wipe Application Study

Description: As part of a pollution prevention program, a study was conducted at Sandia National Laboratories and at the Amarillo, ''Pantex Plant'' to identify a suitable replacement solvent(s) for cleaning hardware during routine maintenance operations. Current cleaning is performed using solvents (e.g. acetone, toluene, MEK, alcohols) that are classified as Resource Conservation and Recovery Act (RCW) materials. The Environmental Protection Agency (EPA) has assigned four characteristics as the criteria for determining whether a material is identified as hazardous under RCRA: Ignitability, Corrosivity, Reactivity and Toxicity. Within the DOE and DoD sector, these solvents are used with hand wipes to clean surfaces prior to O-ring replacement, to remove decals for new labeling, to clean painted surfaces prior to reconditioning, and for other general maintenance purposes. In some cases, low level radioactive contamination during cleaning necessitates that the RCIL4 solvent-containing wipes be classified as mixed waste. To avoid using RCRA materials, cleaning candidates were sought that had a flashpoint greater than 140 F, a pH between 2.5 and 12.5, and did not fail the reactivity and toxicity criteria. Three brominated cleaners, two hydrofluoroether azeotropes and two aliphatic hydrocarbon cleaner formulations were studied as potential replacements. Cleaning efficacy, materials compatibility, corrosion and accelerated aging studies were conducted and used to screen potential candidates. Hypersolve NPB (an n-propyl bromide based formulation) consistently ranked high in removing typical contaminants for weapons applications.

Lasagna{trademark} soil remediation

Description: Lasagna{trademark} is an integrated, in situ remediation technology being developed by an industrial consortium consisting of Monsanto, E. I. DuPont de Nemours & Co., Inc. (DuPont), and General Electric, with participation from the Department of Energy (DOE) Office of Environmental Management, Office of Science and Technology (EM-50), and the Environmental Protection Agency (EPA) Office of Research and Development (Figure 1). Lasagna{trademark} remediates soils and soil pore water contaminated with soluble organic compounds. Lasagna{trademark} is especially suited to sites with low permeability soils where electroosmosis can move water faster and more uniformly than hydraulic methods, with very low power consumption. The process uses electrokinetics to move contaminants in soil pore water into treatment zones where the contaminants can be captured or decomposed. Initial focus is on trichloroethylene (TCE), a major contaminant at many DOE and industrial sites. Both vertical and horizontal configurations have been conceptualized, but fieldwork to date is more advanced for the vertical configuration.

Description: The contained recovery of oily waste (CROW{trademark}) process developed by Western Research Institute (WRI) removes organic contaminants from the subsurface by means of adaptation of technology used for secondary and heavy oil recovery. The CROW technology was successfully tested in the laboratory as part of a project for the US Environmental Protection Agency (EPA) SITE Program's Emerging Technology Program (Johnson and Guffey 1990). The experimental program consisted of several one- and three-dimensional hot-water flushing tests to simulate the process. The tests were conducted with organically saturated, sand packed tubes and blocks. These experiments showed that hot-water flushing could reduce the organic contaminant content by approximately 60%. Further testing with totally biodegradable chemicals showed that the removal rate could be increased to approximately 90%. Additional testing showed that the CROW process did not hinder but helped in the biodegradation of the residual organics (Johnson and Leuschner 1992). Based on the laboratory performance of the process, the EPA advanced the process to the SITE Demonstration Program. Further development of the process has included the completion of a pilot test at an active wood treatment facility. The pilot test provided additional information for the design of a field-scale remediation effort in addition to verifying several of the prepilot design specifications and predictions. Verified by the pilot test were the abilities to: (1) establish and maintain desired injection and extraction rates, (2) heat the test area to the desired temperature, (3) achieve non-aqueous phase liquid (NAPL) removal rates equivalent to laboratory rates, and (4) show that the produced fluid can be treated for reinfection or disposal (Fahy et al. 1992).

Site Screening and Technical Guidance for Monitored Natural Attenuation at DOE Sites

Description: Site Screening and Technical Guidance for Monitored Natural Attenuation at DOE Sites briefly outlines the biological and geochemical origins of natural attenuation, the tendency for natural processes in soils to mitigate contaminant transport and availability, and the means for relying on monitored natural attenuation (MNA) for remediation of contaminated soils and groundwaters. This report contains a step-by-step guide for (1) screening contaminated soils and groundwaters on the basis of their potential for remediation by natural attenuation and (2) implementing MNA consistent with EPA OSWER Directive 9200.4-17. The screening and implementation procedures are set up as a web-based tool (http://www.sandia.gov/eesector/gs/gc/na/mnahome.html) to assist US Department of Energy (DOE) site environmental managers and their staff and contractors to adhere to EPA guidelines for implementing MNA. This document is intended to support the Decision Maker's Framework Guide and Monitoring Guide both to be issued from DOE EM-40. Further technical advances may cause some of the approach outlined in this document to change over time.

Corrective Action Decision Document, Area 15 Environmental Protection Agency Farm Laboratory Building, Corrective Action Unit No. 95, Revision 0

Description: This report is the Corrective Action Decision Document (CADD) for the Nevada Test Site (NTS) Area 15 U.S. Environmental Protection Agency (EPA) Farm, Laboratory Building (Corrective Action Unit [CAU] No. 95), at the Nevada Test Site, Nye County, Nevada. The scope of this CADD is to identify and evaluate potential corrective action alternatives for the decommissioning and decontamination (D and D) of the Laboratory Building, which were selected based on the results of investigative activities. Based on this evaluation, a preferred corrective action alternative is recommended. Studies were conducted at the EPA Farm from 1963 to 1981 to determine the animal intake and retention of radionuclides. The main building, the Laboratory Building, has approximately 370 square meters (4,000 square feet) of operational space. Other CAUS at the EPA Farm facility that will be investigated and/or remediated through other environmental restoration subprojects are not included in this CADD, with the exception of housekeeping sites. Associated structures that do not require classification as CAUS are considered in the evaluation of corrective action alternatives for CAU 95.

The waste isolation pilot plant regulatory compliance program

Description: The passage of the WIPP Land Withdrawal Act of 1992 (LWA) marked a turning point for the Waste Isolation Pilot Plant (WIPP) program. It established a Congressional mandate to open the WIPP in as short a time as possible, thereby initiating the process of addressing this nation`s transuranic (TRU) waste problem. The DOE responded to the LWA by shifting the priority at the WIPP from scientific investigations to regulatory compliance and the completion of prerequisites for the initiation of operations. Regulatory compliance activities have taken four main focuses: (1) preparing regulatory submittals; (2) aggressive schedules; (3) regulator interface; and (4) public interactions

Environmental research brief: Pollution prevention assessment for a manufacturer of metal fasteners

Description: The US Environmental Protection Agency (EPA) has funded a pilot project to assist small and medium-size manufacturers who want to minimize their generation of waste but who lack the expertise to do so. In an effort to assist these manufacturers Waste Minimization Assessment Centers (WMACs) were established at selected universities and procedures were adapted from the EPA Waste Minimization Opportunity Assessment Manual (EPA/625/7-88/003, July 1988). That document has been superseded by the Facility Pollution Prevention Guide (EPA/600/R-92/088, May 1992). The WMAC team at the University of Tennessee performed an assessment at a plant that manufactures various types of metal fasteners for automobiles, furniture, and appliances. Products are manufactured from steel, brass, copper, and aluminum wire and rod stock in two production lines-large part production and small part production. In large part production, header machines press wire stock into specific product shapes which are washed, machined, and in some cases heat-treated and polished. Small parts are manufactured from wire and rod stock in a series of machining operations, then washed, heat treated and polished, before shipment to an outside firm for surface finishing. The team`s report, detailing findings and recommendations indicated that a large amount of plant oil waste is shipped off-site for fuels blending and a significant quantity of oily sludge waste is shipped offsite for disposal as non-hazardous waste. Large cost savings can be achieved by the plant through the use of alternative methods of removing metal chips from parts, thereby reducing intermediate washings.

Summary of scientific investigations for the Waste Isolation Pilot Plant

Description: The scientific issues concerning disposal of radioactive wastes in salt formations have received 40 years of attention since the National Academy of Sciences (NAS) first addressed this issue in the mid-50s. For the last 21 years, Sandia National Laboratories (SNL) have directed site specific studies for the Waste Isolation Pilot Plant (WIPP). This paper will focus primarily on the WIPP scientific studies now in their concluding stages, the major scientific controversies regarding the site, and some of the surprises encountered during the course of these scientific investigations. The WIPP project`s present understanding of the scientific processes involved continues to support the site as a satisfactory, safe location for the disposal of defense-related transuranic waste and one which will be shown to be in compliance with Environmental Protection Agency (EPA) standards. Compliance will be evaluated by incorporating data from these experiments into Performance Assessment (PA) models developed to describe the physical and chemical processes that could occur at the WIPP during the next 10,000 years under a variety of scenarios. The resulting compliance document is scheduled to be presented to the EPA in October 1996 and all relevant information from scientific studies will be included in this application and the supporting analyses. Studies supporting this compliance application conclude the major period of scientific investigation for the WIPP. Further studies will be of a ``confirmatory`` and monitoring nature.

Environmental Research Brief: Pollution prevention assessment for a manufacturer of pharmaceuticals

Description: The Waste Minimization Assessment Center at Colorado State Univ. performed an assessment at a plant that manufactures intermediates for pharmaceuticals and other chemicals. Waste streams generated in the greatest quantities are waste solvents that are reused onsite, incinerated as fuel in an onsite boiler, or shipped offsite for disposal. The greatest cost savings could be achieved by reusing additional amounts of methylene chloride in the plant. This research brief discusses the process, existing waste management practices, pollution prevention opportunities, and gives additional recommendations. Tables summarize current waste generation and recommended waste minimization opportunities.

A comparison of hydrogen vehicle storage options using the EPA urban driving schedule

Description: The three standard options for the storage of hydrogen fuel on passenger vehicles are compressed gas, metal hydride and cryogenic liquid storage. The weight of the hydrogen storage system affects the performance of the vehicle. We examine vehicle performance as a function of hydrogen storage system type and capacity. Three vehicles are modeled, a metro commuter, a mid size sedan and a full size van. All vehicles are powered by a fuel cell and an electric drive train. The impact of auxiliary power requirements for air conditioning is also examined. In making these comparisons it is necessary to assume a driving cycle. We use the United States Environmental Protection Agency (EPA) urban dynamometer driving schedule in all simulations to represent typical urban driving conditions.

Using stakeholder input to develop environmental regulatory approaches : a case study.

Description: Many regulated entities today charge that environmental regulations have become inefficient and could be made more cost effective. The US Environmental Protection Agency (EPA) has identified several initiatives to help ''reinvent'' environmental regulations and address those charges. At the same time, the President and others are pursuing the development and use of new environmental technologies. Reflecting these trends, Argonne National Laboratory is helping develop a prototype multimedia environmental regulatory program for petroleum refineries operating in the Mure. The project differs from other regulatory reinvention efforts in that it is Mure-oriented and, as a result, may result in recommendations that depart significantly from those from existing regulatory systems. This paper notes the importance of communicating environmental information when developing and implementing regulatory approaches. Two approaches--one goal-based and the other risk-based--are being considered for the prototype regulatory program. Both are site-specific, and the implementation of both requires a significant amount of communication among refiners, regulators, and other stakeholders. Of even greater importance, however, is the communication involved in the development of these approaches. Because these new regulatory approaches could fundamentally change the way regulated entities operate, ideas and concerns of groups likely to be affected by the regulatory prototypes need to be considered. This case study focuses on the use of structured workshops involving representatives from three separate interest groups--refiners, regulators, and the environmental community--in developing regulatory approaches. At the time of this writing, workshops have been held with two groups, and a third is being scheduled. This paper describes the process for eliciting interaction, highlights the results of the workshops, and discusses ways to optimize approaches for obtaining and using environmental communications. Results and lessons learned may be applied to improve regulations in other sectors.

Corrective Action Investigation Plan for Corrective Action Unit 135: Area 25 Underground Storage Tanks, Nevada Test Site, Nevada

Description: This CAIP presents a plan to investigate the nature and extent of the contaminants of potential concern (COPCs) at CAU 135. The purpose of the corrective action investigation described in this CAIP is to: (1) Identify the presence and nature of COPCs; (2) Determine the location of radiological contamination within the vault and determine the extent of COPCs in the sump area and on the floor; and (3) Provide sufficient information and data to develop and evaluate appropriate corrective actions for CAS 25-02-01. This CAIP was developed using the U.S. Environmental Protection Agency's (EPA) Data Quality Objectives (DQOs) (EPA, 1994) process to clearly define the goals for collecting environmental data, to determine data uses, and to design a data collection program that will satisfy these uses. A DQO scoping meeting was held prior to preparation of this plan; a brief summary of the DQOs is presented in Section 3.4. A more detailed summary of the DQO process and results is included in Appendix A.
