November 20, 2004 t Mr. Bill Thomson Northside Carting 210 Holt Road North Andover,MA 01845 PRINCIPALS Subject: Updates to Air Quality Modeling Report for Proposed Salem Transfer Station- Revision Theodore A$amen,PE Margaret 8 Briggs Dear Mr.Thomson: Michael E Bashi,CCM Samuel G Mygatt,LLB Attached is a revised Attachment A,emission calculations with larger font. We have also revised the days per week to 5.5 instead of 5, which increases the PM-10 to Date Racxynski,PE 0.64 tpy, and PM-2.5 to 0.26 tpy. This slightly improves the cost effectiveness of Cindy Schiessinger the fabric filter, but it is still 10 times more expensive than MassDEP would consider cost effective. This does not change any of the air modeling results. Lester B Smith,Jr Victoria N Fletcher,RLA I apologize for the small font on the calculations. It was not intentional.

November 18, 2009 Mr. Bill Thomson Northside Carting 210 Holt Road North Andover, MA 01845 Subject: Updates to Air Quality Modeling Report for Proposed Salem Transfer PRINCIPALS Station Theodore A Borten,PE Margaret B Briggs Dear Mr. Thomson: Michael E Guski,CCM To follow up on the hearing at the Salem Board of Health on November 10, 2009, Samuel G Mygatt,LLB Epsilon has updated the air modeling as follows: Dale 7 Raczynski,PE # We have increased the future build case from 194 truck trips p per day to 230 Cindy Schlessinger truck trips per day to account for a daily peak of 500 ton per day (tpd) of Lester 8 Smith,Jr material received at the facility. This increased the maximum total concentration from Table 4 of the report very slightly as shown in the Victoria H Fletcher,RLA revised Table 4 below. The future facility (°TBI") truck contribution to the Robert 0'Neal,INCE total remains extremely small at less than 0.02 pgtm' for all cases. Also the maximum total concentration at receptor 9 (representing homes at corner of. ASSOCIATES First and Swampscott , southeast of facility), the closest residential receptor Andrew D Magee has been added to Table 5, and is very small at less than 0.03 pglm'for PM- 2.5, 24-hr average as an example. Michael D Howard,PWS e We have now modeled the PM-10 and PM-2.5 emissions from the building Laura E Rome operations using the U.S. EPA recommended AERMOD model. Calculations of these emissions are in Attachment A, and are estimated at 0.58 tons per year (tpy) of PM-10, and 0.24 tpy of PM-2.5 after control with water mists at a control efficiency of 50%. We have assumed that 10% of the PM emissions are released thru an open truck door at the north side of 3 Clock Tower Place,Suite 250 the building, and that 90% are vented thru a new stack, 2.5 feet diameter, Maynard, MA 01754 45 feet high above the tipping floor base at a flow rate of 15,000 actual www.epsilonassociates.tom cubic feet per minute (ACFM). The 10% from the door is based on the use 9788977100 of fast closing doors that are closed most of the time during indoor rm 978 897 0099 operations. Even when open, there will be a negative pressure thru the door that should keep most of the PM contained within the building and then release via the stack,which improves dispersion. On this basis, I believe the 10% is conservatively high, and that more than 90% of the PM-10 and PM- 2.5 emissions will be released thru the stack. The emissions estimates SERBIAN= 1 ! HIM ENGINEERS 13 ENVIRONMENTAL r.ONSIIITANT( Mr. Bill Thomson Northside Carting November 18, 2009 include the trucks and loader inside the building. A brief description of the air quality modeling is presented in Attachment B. The maximum impacts from the building emissions, including thru the door and the stack are shown in Table 4, and are well within the National Ambient Air Quality Standards (NAAQS). The NAAQS were developed by the U.S. Environmental Protection Agency (EPA) to protect the public health against adverse health effects including the health of sensitive populations such as asthmatics, children and the elderly with a margin of safety. Table 4 also shows the maximum impacts from the building emissions at receptor 9, the closest residential receptor, also well below the NAAQS. Northside Carting has carefully considered what type of air pollution control equipment, if any, will be appropriate for the facility. If the potential PM-10 or PM-2.5 emissions were greater than 1 tpy, then MassDEP would require an Air Plan Approval and require the use of Best Available Control Technology (SACT). For a project of this size and type, DEP would likely not require a formal BACT analysis, where the most stringent, technically feasible control technology is evaluated to determine whether it is cost effective in terms of$/ton of pollutant removed. If the top technology is not cost effective,the next most stringent is evaluated or selected as BACT. DEP makes the final determination of BACT. The standard design for transfer stations has been water mist suppression as proposed for this facility, and we believe this would be found to be BACT by DEP if subject to Air Plan Approval. However, we have conducted a preliminary BACT analysis, also included in the attached calculations. We find that a fabric filter (or baghouse), which would be the most stringent or top technology is not cost effective by a wide margin (nearly ten times MaSsDEP'S cost effectiveness threshold) and should not be required.

The latest version of the EPA approved air quality model, AERMOD model (09292), was used for this analysis. The AERMOD model is a steady state plume model using Gaussian distributions that calculates concentrations at each receptor for every hour in the year. The model is designed for rural or urban applications and can be used with a rectangular or polar system of receptors that are allowed to vary with terrain. AERMOD was run with the regulatory default options with five years of meteorological data (2004-2008) of hourly surface observations from Boston's Logan International Airport in conjunction with twice daily upper air soundings from Gray, ME. The meteorological data was processed with the AERMET processor, using AERSURFACE to characterize the surface characteristics around the airport for input to AERMET. The area within 3 km of the transfer station was determined to be rural for dispersion characteristics based on the Auer land use typing scheme. Therefore rural dispersion coefficients were used in the AERMOD modeling. The PM10 and PM2.5 emissions from the building operations were modeled. We have assumed that 10% of the PM emissions are released thru an open truck door at the north side of the building, and that 90% are vented thru a new stack adjacent to the south side of the building, 2.5 feet diameter, 45 feet high above the tipping floor base at a flow rate of 15,000 actual cubic feet per minute (ACFM). The building is 98' x 100' with a height of 35'. The stack emissions are assumed to be at ambient temperature. The stack will be influenced by aerodynamic downwash caused by the building. The BPIP-Prime model was run to characterize the building parameters for input into AERMOD. The emission vented through the garage door was modeled as a volume source release. The dimensions of the garage door are 15'00'. Figure 1 shows the facility layout as modeled in AERMOD. The building, sources, and fence line receptors are shown. The source parameters and emission rates are summarized in Table 1.

Receptors were located along the facility fence line at 10 m spacing, as well as an extended grid parallel to the fence line at 25 meter intervals out to 100 meters. In addition, a nested Cartesian grid extending out to 2 kilometers in each direction was used. The receptor spacing in the grid was 100 m out to 1 km, and 200 m out to 2 km. The terrain elevation for each receptor was obtained electronically for the USGS National Elevation Data (NED). The AERMAP terrain processor was used. Elevations for the fence line receptors were entered by hand based on contour data in the immediate vicinity of the project. The AERMOD receptors are presented in Figures 2 and 3. The predicted air quality levels of the PM10 and PM2.5 impacts due to the operations at the transfer building were assessed through the modeling analysis. The AERMOD modeled impacts are added to the measured background from the Kenmore Square monitoring station for PM10, and the Lynn monitor for PM2.5, then compared to the NAAQS. Table 2 summarizes the AERMOD predicted particulate impacts from the stationary sources combined with the maximum mobile source impacts modeled with CAL3QHCR. Note that the maximum from each model are conservatively added together, and they are not matched in time or space. Table 3 summarizes the same impacts at the nearest residential receptor. An B-2 Mr. Bill Thomson Northside Carting November 18, 2009 The total combined impacts of particulate matter are less than the National Ambient Air Quality Standards for both PM10 and PM2.5.

November 18, 2009 Mr. Bill Thomson Northside Carting 210 Holt Road North Andover, MA 01845 Subject: Updates to Air Quality Modeling Report for Proposed Salem Transfer PRINCIPALS Station Theodore A Borten,PE Margaret B Briggs Dear Mr. Thomson: Michael E Guski,CCM To follow up on the hearing at the Salem Board of Health on November 10, 2009, Samuel G Mygatt,LLB Epsilon has updated the air modeling as follows: Dale T Raczynski,PE • We have increased the future build case from 194 truck trips per day to 230 Cindy Schlessinger truck trips per day to account for a daily peak of 500 ton per day (tpd) of Lester B Smith,Jr material received at the facility. This increased the maximum total concentration from Table 4 of the report very slightly as shown in the Victoria H Fletcher,RLA revised Table 4 below. The future facility MIN) truck contribution to the Robert 0`Neal,INCE total remains extremely small at less than 0.02 pglm' for all cases. Also the maximum total concentration at receptor 9 (representing homes at corner of. ASSOCIATES First and Swampscott , southeast of facility), the closest residential receptor Andrew 0 Magee has been added to Table 5, and is very small at less than 0.03 pgtm'for PM- 2.5, 24-hr average as an example. Michael 0 Howard,PWS • We have now modeled the PM-10 and PM-2.5 emissions from the building Laura E Rome operations using the U.S. EPA recommended AERMOD model. Calculations of these emissions are in Attachment A, and are estimated at 0.58 tons per year (tpy) of PM-10, and 0.24 tpy of PM-2.5 after control with water mists at a control efficiency of 50%. We have assumed that 10% of the PM emissions are released thru an open truck door at the north side of 3 Clock Tower Place,Suite 250 the building, and that 90% are vented thru a new stack, 2.5 feet diameter, Maynard, MA 01754 45 feet high above the tipping floor base at a flow rate of 15,000 actual www.epsitonassociates.com cubic feet per minute (ACFM). The 10% from the door is based on the use 9788977100 of fast closing doors that are closed most of the time during indoor rAa 978 897 0099 operations. Even when open, there will be a negative pressure thru the door that should keep most of the PM contained within the building and then release via the stack,which improves dispersion. On this basis, I believe the 10% is conservatively high, and that more than 90% of the PM-10 and PM- 2.5 emissions will be released thru the stack. The emissions estimates + I ± , ENGINEERS IMENVIRGNMENTALCONSUITANTS Mr. Bill Thomson Northside Carting November 18,2009 include the trucks and loader inside the building. A brief description of the air quality modeling is presented in Attachment B. • The maximum impacts from the building emissions, including thru the door and the stack are shown in Table 4, and are well within the National Ambient Air Quality Standards (NAAQS). The NAAQS were developed by the U.S. Environmental Protection Agency (EPA) to protect the public health against adverse health effects including the health of sensitive populations such as asthmatics, children and the elderly with a margin of safety. Table 4 also shows the maximum impacts from the building emissions at receptor 9, the closest residential receptor, also well below the NAAQS. • Northside Carting has carefully considered what type of air pollution control equipment, if any, will be appropriate for the facility. If the potential PM-10 or PM-2.5 emissions were greater than 1 tpy, then MassDEP would require an Air Plan Approval and require the use of Best Available Control Technology (BACT). For a project of this size and type, DEP would likely not require a formal BACT analysis, where the most stringent, technically feasible control technology is evaluated to determine whether it is cost effective in terms of$/ton of pollutant removed. If the top technology is not cost effective,the next most stringent is evaluated or selected as BACT. DEP makes the final determination of BACT. The standard design for transfer stations has been water mist suppression as proposed for this facility, and we believe this would be found to be BACT by DEF if subject to Air Plan Approval. However, we have conducted a preliminary BACT analysis, also included in the attached calculations. We find that a fabric filter (or baghouse), which would be the most stringent or top technology is not cost effective by a wide margin (nearly ten times MassDEP's cost effectiveness threshold) and should not be required.

The latest version of the EPA approved air quality model, AERMOD model (09292), was used for this analysis. The AERMOD model is a steady state plume model using Gaussian distributions that calculates concentrations at each receptor for every hour in the year. The model is designed for rural or urban applications and can be used with a rectangular or polar system of receptors that are allowed to vary with terrain. AERMOD was run with the regulatory default options with five years of meteorological data (2004-2008) of hourly surface observations from Boston's Logan International Airport in conjunction with twice daily upper air soundings from Gray, ME.The meteorological data was processed with the AERMET processor, using AERSURFACE to characterize the surface characteristics around the airport for input to AERMET. The area within 3 km of the transfer station was determined to be rural for dispersion characteristics based on the Auer land use typing scheme. Therefore rural dispersion coefficients were used in the AERMOD modeling. The PM10 and PM2.5 emissions from the building operations were modeled. We have assumed that 10% of the PM emissions are released thru an open truck door at the north side of the building, and that 90% are vented thru a new stack adjacent to the south side of the building, 2.5 feet diameter, 45 feet high above the tipping floor base at a flaw rate of 15,000 actual cubic feet per minute (ACFM). The building is 98' x 100' with a height of 35'. The stack emissions are assumed to be at ambient temperature. The stack will be influenced by aerodynamic downwash caused by the building. The BPIP-Prime model was run to characterize the building parameters for input into AERMOD. The emission vented through the garage door was modeled as a volume source release. The dimensions of the garage door are 15'00'. Figure 1 shows the facility layout as modeled in AERMOD. The building, sources, and fence fine receptors are shown. The source parameters and emission rates are summarized in Table 1.

Receptors were located along the facility fence line at 10 m spacing, as well as an extended grid parallel to the fence line at 25 meter intervals out to 100 meters. In addition, a nested Cartesian grid extending out to 2 kilometers in each direction was used. The receptor spacing in the grid was 100 m out to 1 km, and 200 m out to 2 km. The terrain elevation for each receptor was obtained electronically for the USGS National Elevation Data (NED). The AERMAP terrain processor was used. Elevations for the fence line receptors were entered by hand based on contour data in the immediate vicinity of the project. The AERMOD receptors are presented in Figures 2 and 3. The predicted air quality levels of the PM10 and PM2.5 impacts due to the operations at the transfer building were assessed through the modeling analysis. The AERMOD modeled impacts are added to the measured background from the Kenmore Square monitoring station for PM10, and the Lynn monitor for PM2.5, then compared to the NAAQS. Table 2 summarizes the AERMOD predicted particulate impacts from the stationary sources combined with the maximum mobile source impacts modeled with CAL3QHCR.

November 18, 2009 Mr. Bill Thomson Northside Carting 210 Holt Road North Andover, MA 01845 Subject: Updates to Air Quality Modeling Report for Proposed Salem Transfer PRINCIPALS Station Theodore A Barten,PE Margaret 8 Briggs Dear Mr. Thomson: Michael E Guski,CCM To follow up on the hearing at the Salem Board of Health on November 10, 2009, Samuel G Mygatt,LLB Epsilon has updated the air modeling as follows: Dale T Racxynski,PE „ We have increased the future build case from 194 truck trips per day to 230 Cindy Scbiessinger truck trips per day to account for a daily peak of 500 ton per day (tpd) of Lester 8 Smith,Jr material received at the facility. This increased the maximum total concentration from Table 4 of the report very slightly as shown in the Victoria H Fletcher,RLA revised Table 4 below. The future facility ("TBI') truck contribution to the Robert 0'Neal,INCE total remains extremely small at less than 0.02 uglm' for all cases. Also the maximum total concentration at receptor 9 (representing homes at corner of ASSOCIATES First and Swampscott , southeast of facility),.the closest residential receptor Andrew D Magee has been added to Table 5, and is very small at less than 0.03/Jglm'for PM- 2.5, 24-hr average as an example. Michael O Howard,PWS • We have now modeled the PM-10 and PM-2.5 emissions from the building Laura E Rome operations using the U.S. EPA recommended AERMOD model. Calculations of these emissions are in Attachment A, and are estimated at 0.58 tons per year (tpy) of PM-10, and 0.24 tpy of PM-2.5 after control with water mists at a control efficiency of 50%. We have assumed that 10% of the PM emissions are released thru an open truck door at the north side of 3 clock Tower Place.Salle 250 the building, and that 90% are vented thru a new stack, 2.5 feet diameter, Maynard,MA 01754 45 feet high above the tipping floor base at a flow rate of 15,000 actual w"Iticsilonassociates.com cubic feet per minute (ACFM). The 10% from the door is based on the use 9788977100 of fast closing doors that are closed most of the time during indoor rAx 978 897 0099 operations. Even when open, there will be a negative pressure thru the door that should keep most of the PM contained within the building and then release via the stack,which improves dispersion. On this basis, I believe the 10% is conservatively high, and that more than 90% of the PM-10 and PM- 2.5 emissions will be released thru the stack. The emissions estimates I Big _ I L ENGINEERS 13 ENVIRONMENTAL CONSIIITANTt Mr. Bill Thomson Northside Carting November 18, 2009 include the trucks and loader inside the building. A brief description of the air quality modeling is presented in Attachment B. • The maximum impacts from the building emissions, including thru the door and the stack are shown in Table 4, and are well within the National Ambient Air Quality Standards (NAAQS). The NAAQS were developed by the U.S. Environmental Protection Agency (EPA) to protect the public health against adverse health effects including the health of sensitive populations such as asthmatics, children and the elderly with a margin of safety. Table 4 also shows the maximum impacts from the building emissions at receptor 9, the closest residential receptor, also well below the NAAQS. • Northside Carting has carefully considered what type of air pollution control equipment, if any, will be appropriate for the facility. If the potential PM-10 or PM-2.5 emissions were greater than 1 tpy, then MassDEP would require an Air Plan Approval and require the use of Best Available Control Technology (BACT). For a project of this size and type, DEP would likely not require a formal BACT analysis, where the most stringent, technically feasible control technology is evaluated to determine whether it is cost effective in terms of$/ton of pollutant removed. If the top technology is not cost effective,the next most stringent is evaluated or selected as BACT. DEP makes the final determination of BACT. The standard design for transfer stations has been water mist suppression as proposed for this facility, and we believe this would be found to be BACT by DEP if subject to Air Plan Approval. However, we have conducted a preliminary BACT analysis, also included in the attached calculations. We find that a fabric filter (or baghouse), which would be the most stringent or top technology is not cost effective by a wide margin (nearly ten times MassDEP's cost effectiveness threshold) and should not be required.

The latest version of the EPA approved air quality model, AERMOD model (09292), was used for this analysis. The AERMOD model is a steady state plume model using Gaussian distributions that calculates concentrations at each receptor for every hour in the year. The model is designed for rural or urban applications and can be used with a rectangular or polar system of receptors that are allowed to vary with terrain. AERMOD was run with the regulatory default options with five years of meteorological data (2004-2008) of hourly surface observations from Boston's Logan International Airport in conjunction with twice daily upper air soundings from Gray, ME. The meteorological data was processed with the AERMET processor, using AER5URFACE to characterize the surface characteristics around the airport for input to AERMET. The area within 3 km of the transfer station was determined to be rural for dispersion characteristics based on the Auer land use typing scheme. Therefore rural dispersion coefficients were used in the AERMOD modeling. The PM10 and PM2.5 emissions from the building operations were modeled. We have assumed that 10% of the PM emissions are released thru an open truck door at the north side of the building, and that 90% are vented thru a new stack adjacent to the south side of the building, 2.5 feet diameter, 45 feet high above the tipping floor base at a flow rate of 15,000 actual cubic feet per minute (ACFM). The building is 98' x 100' with a height of 35'. The stack emissions are assumed to be at ambient temperature. The stack will be influenced by aerodynamic downwash caused by the building. The BPIP-Prime model was run to characterize the building parameters for input into AERMOD. The emission vented through the garage door was modeled as a volume source release. The dimensions of the garage door are 15'x30'. Figure 1 shows the facility layout as modeled in AERMOD. The building, sources, and fence line receptors are shown. The source parameters and emission rates are summarized in Table 1.

Receptors were located along the facility fence line at 10 m spacing, as well as an extended grid parallel to the fence line at 25 meter intervals out to 100 meters. In addition, a nested Cartesian grid extending out to 2 kilometers in each direction was used. The receptor spacing in the grid was 100 m out to 1 km, and 200 m out to 2 km. The terrain elevation for each receptor was obtained electronically for the USGS National Elevation Data (NED). The AERMAP terrain processor was used. Elevations for the fence line receptors were entered by hand based on contour data in the immediate vicinity of the project. The AERMOD receptors are presented in Figures 2 and 3. The predicted air quality levels of the PM10 and PM2.5 impacts due to the operations at the transfer building were assessed through the modeling analysis. The AERMOD modeled impacts are added to the measured background from the Kenmore Square monitoring station for PM10, and the Lynn monitor for PM2.5, then compared to the NAAQS. Table 2 summarizes the AERMOD predicted particulate impacts from the stationary sources combined with the maximum mobile source impacts modeled with CAL3QHCR. Note that the maximum from each model are conservatively added together, and they are not matched in time or space. Table 3 summarizes the same impacts at the nearest residential receptor. Aft 8-2 Mr. Bill Thomson Northside Carting November 18, 2009 The total combined impacts of particulate matter are less than the National Ambient Air Quality Standards for both PM10 and PM2.5.

November 18, 2009 Mr. Bill Thomson Northside Carting 210 Holt Road North Andover, MA 01845 Subject: Updates to Air Quality Modeling Report for Proposed Salem Transfer PRINCIPALS Station Theodore A Barten,PE Margaret B Briggs Dear Mr. Thomson: Michael E Guski,CCM To follow up on the hearing at the Salem Board of Health on November 10, 2009, Samuel G Mygatt,LLB Epsilon has updated the air modeling as follows: Dale T Raczynskl,PE 0 We have increased the future build case from 194 truck trips per day to 230 Cindy Schlessinger truck trips per day to account for a daily peak of 500 ton per day (tpd) of Lester 8 smith,Jr material received at the facility. This increased the maximum total concentration from Table 4 of the report very slightly as shown in the Victoria H Fletcher,FLA revised Table 4 below. The future facility (°TBI") truck contribution to the Roltert 0'Neal,INCE total remains extremely small at less than 0.02 ug/m' for all cases. Also the maximum total concentration at receptor 9 (representing homes at corner of ASSOCIATES First and Swampscott , southeast of facility),,the closest residential receptor Andrew D Magee has been added to Table 5, and is very small at less than 0.03 ug/m'for PM- 2.5, 24-hr average as an example. Michael D Howard,PWS In We have now modeled the PM-10 and PM-2.5 emissions from the building Laura E Rome operations using the U.S. EPA recommended AERMOD model. Calculations of these emissions are in Attachment A, and are estimated at 0.58 tons per year (tpy) of PM-10, and 0.24 tpy of PM-2.5 after control with water mists at a control efficiency of 50%. We have assumed that 10% of the PM emissions are released thru an open truck door at the north side of 3 clock Tower Place, suite 250 the building, and that 90% are vented thru a new stack, 2.5 feet diameter, Maynard, MA 01754 45 feet high above the tipping floor base at a flow rate of 15,000 actual www.epsilonassociates.com cubic feet per minute (ACFM). The 10% from the door is based on the use 9708977100 of fast closing doors that are closed most of the time during indoor £AX 978 897 0099 operations. Even when open, there will be a negative pressure thru the door that should keep most of the PM contained within the building and then release via the stack, which improves dispersion. On this basis, I believe the 10% is conservatively high, and that more than 90% of the PM-10 and PM- 2.5 emissions will be released thru the stack. The emissions estimates i ENGINEERS 03 ENVIRONMENTAL CONgOl tAN 1S Mr. Bill Thomson Northside Carting November 18, 2009 include the trucks and loader inside the building.A brief description of the air quality modeling is presented in Attachment B. • The maximum impacts from the building emissions, including thru the door and the stack are shown in Table 4, and are well within the National Ambient Air Quality Standards (NAAQS). The NAAQS were developed by the U.S. Environmental Protection Agency (EPA) to protect the public health against adverse health effects including the health of sensitive populations such as asthmatics, children and the elderly with a margin of safety. Table 4 also shows the maximum impacts from the building emissions at receptor 9, the closest residential receptor, also well below the NAAQS. • Northside Carting has carefully considered what type of air pollution control equipment, if any, will be appropriate for the facility. If the potential PM-10 or PM-2.5 emissions were greater than 1 tpy, then MassDEP would require an Air Plan Approval and require the use of Best Available Control Technology (SACT). For a project of this size and type, DEP would likely not require a formal BACT analysis, where the most stringent, technically feasible control technology is evaluated to determine whether it is cost effective in terms of$/ton of pollutant removed. If the top technology is not cost effective, the next most stringent is evaluated or selected as SACT. DEP makes the final determination of SACT. The standard design for transfer stations has been water mist suppression as proposed for this facility, and we believe this would be found to be BACT by DEP if subject to Air Plan Approval. However, we have conducted a preliminary BACT analysis, also included in the attached calculations. We find that a fabric filter (or baghouse), which would be the most stringent or top technology is not cost effective by a wide margin (nearly ten times MassDEP's cost effectiveness threshold)and should not be required.

The AERMOD model is a steady state plume model using Gaussian distributions that calculates concentrations at each receptor for every hour in the year. The model is designed for rural or urban applications and can be used with a rectangular or polar system of receptors that are allowed to vary with terrain. AERMOD was run with the regulatory default options with five years of meteorological data (2004-2008) of hourly surface observations from Boston's Logan International Airport in conjunction with twice daily upper air soundings from Gray, ME. The meteorological data was processed with the AERMET processor, using AERSURFACE to characterize the surface characteristics around the airport for input to AERMET. The area within 3 km of the transfer station was determined to be rural for dispersion characteristics based on the Auer land use typing scheme. Therefore rural dispersion coefficients were used in the AERMOD modeling. The PM10 and PM2.5 emissions from the building operations were modeled. We have assumed that 10% of the PM emissions are released thru an open truck door at the north side of the building, and that 90% are vented thru a new stack adjacent to the south side of the building, 2.5 feet diameter, 45 feet high above the tipping floor base at a flow rate of 15,000 actual cubic feet per minute (ACFM). The building is 98' x 100' with a height of 35'. The stack emissions are assumed to be at ambient temperature. The stack will be influenced by aerodynamic downwash caused by the building. The BPIP-Prime model was run to characterize the building parameters for input into AERMOD. The emission vented through the garage door was modeled as a volume source release. The dimensions of the garage door are 15'00'. Figure 1 shows the facility layout as modeled in AERMOD. The building, sources, and fence line receptors are shown. The source parameters and emission rates are summarized in Table 1. Att 8.1 Mr. Bill Thomson Northside Carting November 18, 2009 !

Receptors were located along the facility fence line at 10 m spacing, as well as an extended grid parallel to the fence line at 25 meter intervals out to 100 meters. in addition, a nested Cartesian grid extending out to 2 kilometers in each direction was used. The receptor spacing in the grid was 100 m out to 1 km, and 200 m out to 2 km. The terrain elevation for each receptor was obtained electronically for the USGS National Elevation Data (NED). The AERMAP terrain processor was used. Elevations for the fence line receptors were entered by hand based on contour data in the immediate vicinity of the project. The AERMOD receptors are presented in Figures 2 and 3. The predicted air quality levels of the PM10 and PM2.5 impacts due to the operations at the transfer building were assessed through the modeling analysis. The AERMOD modeled impacts are added to the measured background from the Kenmore Square monitoring station for PM10, and the Lynn monitor for PM2.5, then compared to the NAAQS. Table 2 summarizes the AERMOD predicted particulate impacts from the stationary sources combined with the maximum mobile source impacts modeled with CAL3QHCR.

Goodman, Esq. Goodman Law Offices 152 Lynnway—Suite 1 E Lynn, Massachusetts 01902 RE: Salem Transfer Station/ Salem Board of Health Public Hearing Dear Attorney Goodman; I am in receipt of your letter of November 10;2009 and associated documents by which you petition to Intervene and Register as an Abutter, on behalf of Mr. Alan Samiljan, for purposes of a public hearing held by the City of Salem, MA Board of Health (the `Board")with regard to a Minor Modification To Site Assignment for the Swampscott Road Transfer Station. I trust you will recall that during the first session of the public hearing that was held on Tuesday November 10, 2009 I, as Hearing Officer, indicated that given the recent submission of your petition the Board did not have the time to appropriately review that submission but was nonetheless, for purposes of proceeding with the hearing only,prepared to temporarily afford your client the courtesy of Intervenor status. Please be aware that this courtesy did not constitute and can not be considered as a waiver by the Board or the City of Salem of any rights or privileges they may have to dispute your clients claim to Abutter/Intervenor status at a later time. I also note that during that hearing you requested that I, as Hearing Officer, rule as to the appropriateness of proceeding with the hearing on the basis that the proposed change to operations at the landfill constitutes a Minor Modification to Site Assignment. As the Board is viewing this matter as a Minor Modification on the basis of several considerations, including a determination by MassDEP that the proposed project does constitute a Minor Modification, it is neither necessary nor appropriate for me to rule on the matter.

ATTORNEYS ADM=SOLELY IN TIE JUR1501CTO61 WHERE LISTED OFFICE 15 LOCATED,UNLESS OTHERWISE NOTED L__ November 24, 2009 Page 2 I am also in receipt of your letter of November I 1 in which you submitted a Motion For Order As To Filing & Service and in which you request copies of projected computer images used at the Public Hearings to be converted into print documents for purposes of including them in the public record. I have requested the Applicant to make such copies and to my knowledge they have been added to the public record at the Salem Public Library and the offices of the Board of Health. You have also requested that all plans and diagrams related to the matter be submitted as "full-sized" documents. Notwithstanding the fact that you have failed to identify what would constitute such a full sized document 1, as Hearing Officer, and for the purposes of the Public Hearing, do not agree that such full-sized documents are essential for appropriate public review and comment. Indeed, there may be some disadvantages to the mandated use of such documents during the public hearing process. Consequently I will rely on the discretion of those submitting documents with regard to the public hearing to decide for themselves what the most appropriate sizing for maps, plans is and other documents.
