United States environmental Protection Agency Office of Water Regulations arid Standards Washington. DC 20460 Water Juna, 198S ------- PREFACE This document is one of a series of preliminary assessments dealing with chemicals of potential concern in municipal sewage sludge. The purpose of these documents is to: (a) summarize the available data for the constituents of potential concern, (b) identify the key environ- mental pathways for each constituent related to a reuse and disposal option (based on hazard indices), and (c) evaluate the conditions under which such a pollutant may pose a hazard. Each document provides a sci- entific basis for making an initial determination of whether a pollu- tant, at levels currently observed in sludges, poses a likely hazard to human health or the environment when sludge is disposed of by any of several methods. These methods include landspreading on food chain or nonfood chain crops, distribution and marketing programs, landfilling, incineration and ocean disposal. These documents are intended to serve as a rapid screening tool to narrow an initial list of pollutants to-those of concern. If a signifi- cant hazard is indicated by this preliminary analysis, a more detailed assessment will be undertaken to better quantify the risk from this chemical and to derive criteria if warranted. If a hazard is shown to be unlikely, no further assessment will be conducted at this time; how- ever, a reassessment will be conducted after initial regulations are finalized. In no case, however, will criteria be derived solely on the basis of information presented in this document. ------- TABLE OP CONTENTS Page PREFACE i 1. INTRODUCTION 1-1 2.

PRELIMINARY HAZARD INDEX CALCULATIONS FOR BERYLLIUM IN MUNICIPAL SEWAGE SLUDGE A-l 111 ------- SECTION 1 INTRODUCTION This preliminary data profile is one of a series of profiles dealing with chemical pollutants potentially of concern in municipal sewage sludges. Beryllium (Be) was initially identified as being of potential concern when sludge is incinerated.* This profile is a compi- lation of information that may be useful in determining whether Be poses an actual hazard to human health or the environment when sludge is disposed of by this method. The focus of this document is the calculation of "preliminary hazard indices" for selected potential exposure pathways, as shown in Section 3. Each index illustrates the hazard that could result from movement of a pollutant by a given pathway to cause a given effect (e.g., sludge -»• air •*• human toxicity). The values and assumptions employed in these calculations tend to represent a reasonable "worst case"; analysis of error or uncertainty has been conducted to a limited degree. The resulting value in most cases is indexed to unity; i.e., values .>! may indicate a potential hazard, depending upon the assumptions of the calculation. The data used for index calculation have been selected or estimated based on information presented in the "preliminary data profile", Section 4. Information in the profile is based on a compilation of the recent literature. An attempt has been made to fill out the profile outline to the greatest extent possible. However, since this is a pre- liminary analysis, the literature has not been exhaustively perused. The "preliminary conclusions" drawn from each index in Section 3 are summarized in Section 2. The preliminary hazard indices will be used as a screening tool to determine which pollutants and pathways may pose a hazard. Where a potential hazard is indicated by interpretation of these indices, further analysis will include a more detailed exami- nation of potential risks as well as an examination of site-specific factors. These more rigorous evaluations may change the preliminary conclusions presented in S'ection 2, which are based on a reasonable "worst case" analysis. The preliminary hazard indices for selected exposure routes pertinent to incineration are included in this profile. The calculation formulae for these indices are shown in the Appendix. The indices are rounded to two significant figures. * Listings were determined by a series of expert workshops convened during March-May, 1984 by the Office of Water Regulations and Standards (OWRS) to discuss landspreading, landfilling, incineration, and ocean disposal, respectively, of municipal sewage sludge. 1-1 ------- SECTION 2 PRELIMINARY CONCLUSIONS FOR BERYLLIUM IN MUNICIPAL SEWAGE SLUDGE The following preliminary conclusions have been derived from the calculation of "preliminary hazard indices", which represent conserva- tive or "worst case" analyses of hazard. The indices and their basis and interpretation are explained in Section 3. Their calculation formulae are shown in the Appendix. I. LANDSPREADINC AND DISTRIBUTION-AND-MARKETING Based on the recommendations of the experts at the OWRS meetings (April-May, 1984), an assessment of this reuse/disposal option is not being conducted at this time. The U.S. EPA reserves the right to conduct such an assessment for this option in the future. II. LANDFILLING Based on the recommendations of the experts at the OWRS meetings (April-May, 1984), an assessment of this reuse/disposal option is not being conducted at this time. The U.S. EPA reserves the right to conduct such an assessment for this option in the future. III. INCINERATION The level of Be contamination in the atmosphere is expected to increase slightly with the incineration of municipal sewage sludge. This is particularly evident when high Be concentration sludge is incinerated at high feed rates (see Index 1). Also, the incineration of municipal sewage sludge appears to slightly increase the carcinogenic hazard associated with the inha- lation of Be. The largest risk increase can be expected when high Be concentration sludge is incinerated at high feed rates with the worst level of stack emissions (see Index 2). IV. OCEAN DISPOSAL Based on the recommendations of the experts at the OWRS meetings (April-May, 1984), an assessment of this reuse/disposal option is not being conducted at this time. The U.S. EPA reserves the right to conduct such an assessment for this option in the future. 2-1 ------- SECTION 3 PRELIMINARY HAZARD INDICES FOR BERYLLIUM IN MUNICIPAL SEWAGE SLUDGE I.

Index of Air Concentration Increment Resulting from Incinerator Emissions (Index 1) 1. Explanation - Shows the degree of elevation of the pollutant concentration in the air due to the incinera- tion of sludge. An input sludge with thermal properties defined by the energy parameter (EP) was analyzed using the BURN model (Camp Dresser and McKee, Inc. (COM), 1984). • This model uses the thermodynamic and mass bal- ance relationships appropriate for multiple hearth incin- erators to relate the input sludge characteristics to the stack gas parameters. Dilution and dispersion of these stack gas releases were described by the U.S. EPA's Industrial Source Complex Long-Term (ISCLT) dispersion model from which normalized annual ground level concen- trations were predicted (U.S. EPA, 1979). The predicted pollutant concentration can then be compared to a ground level concentration used to assess risk. 2. Assumptions/Limitations - The fluidized bed incinerator was not chosen due to a paucity of available data. Gradual plume rise, stack tip downwash, and building wake effects are appropriate for describing plume behavior. Maximum hourly impact values can be translated into annual average values. 3. Data Used and Rationale a. Coefficient to correct for mass and time units (C) = 2.78 x 10~7 hr/sec x g/mg 3-1 ------- b. Sludge feed rate (DS) i. Typical = 2660 kg/hr (dry solids input) A feed rate of 2660 kg/hr DW represents an average dewatered sludge feed rate into the furnace. This feed rate would serve a commun- ity of approximately 400,000 people. This rate was incorporated into the U.S. EPA-ISCLT model based on the following input data: EP = 360 Ib H20/mm BTU Combustion zone temperature - 1400°F Solids content - 28% Stack height - 20 m Exit gas velocity - 20 m/s Exit gas temperature - 356.9°K (183°F) Stack diameter - 0.60 m ii. Worst = 10,000 kg/hr (dry solids input) A feed rate of 10,000 kg/hr DW represents a higher feed rate and would serve a major U.S. city. This rate was incorporated into the U.S. EPA-ISCLT model based on the following input data: EP = 392 Ib H20/mm BTU Combustion zone temperature - 1400°F Solids content - 26.6% Stack height - 10 m Exit gas velocity - 10 m/s Exit gas temperature - 313.8°K (105°F) Stack diameter - 0.80 m c. Sludge concentration of pollutant (SC) Typical 0.313 mg/kg DW Worst 1.168 mg/kg'DW Median and 95th percentile (typical and worst) were statistically derived from data presented by a sur- vey of sludge concentration of 40 publicly-owned treatment works (POTWs) (U.S. EPA, 1982). (See Section 4, p. 4-1.) d. Fraction of pollutant emitted through stack (FM) Typical 0.01 (unitless) Worst ' 0.03 (unitless) Emission estimates may vary considerably between sources; therefore, the values used are based on a U.S. EPA 10-city incineration study (Farrell and 3-2 ------- Wall, 1981). Where data were not available from the EPA study, a more recent report which thoroughly researched heavy metal emissions was utilized (CDM, 1983). e. Dispersion parameter for estimating maximum annual ground level concentration (DP) Typical 3.4 yg/m3 Worst 16.0 Ug/m3 The dispersion parameter is derived from the U.S. EPA-ISCLT short-stack model. f. Background concentration of pollutant in urban air (BA) = 0.00025 Ug/m3 Values for 12 cities with populations >500,000 were averaged. The range of background concentrations for Be was from 0.0001 to 0.0005 Ug/m3 (U.S. EPA, 1978). (See Section 4, p. 4-3.) A. Index 1 Values Sludge Feed Fraction of Rate (kg/hr DW)a Pollutant Emitted Sludge Through Stack Concentration 0 2660 10,000 Typical Typical Worst 1.0 1.0 1.0 1.1 1.6 3.1 Worst Typical 1.0 1.1 2.7 Worst 1.0 1.4 7.2 aThe typical (3.4 Ug/m3) and worst (16.0 Ug/m3) disper- sion parameters will always correspond, respectively, to the typical (2b60 kg/hr DW) -and worst (10,000 kg/hr DW) sludge feed rates. 5. Value Interpretation - Value equals factor by which expected air concentration exceeds background levels due to incinerator emissions. 6. Preliminary Conclusion - The level of Be contamination in the atmosphere is expected to increase slightly with the incineration of municipal sewage sludge. This is particularly evident when high Be concentration sludge is incinerated at high feed rates. 3-3 ------- B. Index of Human Cancer Risk Resulting from Inhalation of Incinerator Emissions (Index 2) 1. Explanation - Shows the increase in human intake expected to result from the incineration of sludge. Ground level concentrations for carcinogens typically were developed based upon assessments published by the U.S. EPA Carcino- gen Assessment Group (CAG). These ambient concentrations reflect a dose level which, for a lifetime exposure, increases the risk of cancer by 10~°. 2. Assumptions/Limitations - The exposed population is assumed to reside within the impacted area for 24 hours/day. A respiratory volume of 20 m3/day is assumed over a 70-year lifetime. 3. Data Used and Rationale a. Index of air concentration increment resulting from incinerator emissions (Index 1) See Section 3, p. 3-3. b. Background concentration of pollutant in urban air (BA) = 0.00025 pg/tn3 See Section 3, p. 3-3. c. Cancer potency = 2.6 (mg/kg/day)~^ The cancer potency value was derived from a study of carcinogenic effects produced by occupational inhal- ation of Be (U.S. 'EPA, 1984). (See Section 4, p. 4-5.) d. Exposure criterion (EC) = 1.35 x 10~3 pg/m3 A lifetime exposure level which would result in a 10~° cancer risk was selected as ground level con- centration against which incinerator emissions are compared. The risk estimates developed by CAG are defined as the lifetime incremental cancer risk in a hypothetical population exposed continuously throughout their lifetime to the stated concentra- tion of the carcinogenic agent. The exposure criterion is calculated using the following formula: 10"6 x 103 pg/mg x 70 kg Cancer potency x 20 m3/day 3-4 ------- 4. Index 2 Values Sludge Feed Fraction of . Rate (kg/hr DW)a Pollutant Emitted Sludge Through Stack Concentration 0 2660 10,000 Typical Typical Worst 0.18 0.18 0.19 0.21 0.29 0.57 Worst Typical 0.18 0.20 0.49 Worst 0.18 0.25 1.3 aThe typical (3.4 ug/m^) and worst (16.0 Ug/m-3) disper- sion parameters will always correspond, respectively, to the typical (2660 kg/hr DW) 'and worst (10,000 kg/hr DW) sludge feed rates. 5. Value Interpretation - Value > 1 indicates a potential increase in cancer risk of > 10~6 (1 per 1,000,000). Comparison with the null index value at 0 kg/hr DW indi- cates the degree to which any hazard is due to sludge incineration, as opposed to background urban air concentration. 6. Preliminary Conclusion - The incineration of municipal sewage sludge appears to slightly increase the carcino- genic hazard associated with the inhalation of Be. The largest risk increase can be expected when high Be con- centration sludge is incinerated at high feed rates with the worst level of stack emissions. IV. OCEAN DISPOSAL Based on the recommendations of the experts at the OWRS meetings (April-May, 1984), an assessment of this reuse/disposal option is not being conducted at this time. The U.S. EPA reserves the right to conduct such an assessment for this option in the future. 3-5 ------- SECTION A PRELIMINARY DATA PROFILE FOR BERYLLIUM IN MUNICIPAL SEWAGE SLUDGE I. OCCURRENCE Be is a moderately rare element, exist- ing naturally only in mineral forms. Commercially, it is used as the metal (35%), as beryllium-copper alloys (50%), as other alloys (10%), and as beryllium oxide ceramic products (5%). The primary non-occupational source of Be exposure is coal combustion. According to 1968 data, an annual total of 148 metric tons of &e is released to the U.S. envi- ronment from a variety of sources with coal com- bustion accounting for 85% of the emissions. A.
