Refer to Drawing 1.1 for a general Project Location Map. The existing facilities in the region owned by Martin Marietta Materials include the Carmel Sand Plant and the North Indianapolis Plant, both located in Carmel, Indiana. Skelly and Loy, Inc. has performed a baseline sound study to determine existing conditions in the area and to assess the potential for increased sound levels as a result of the proposed expansion. Noise monitoring was performed at several locations (September 16 and 17,2003) adjacent to the existing Carmel Sand Plant to determine contributions from operations to the local acoustical environment. Computer noise modeling was performed to assess the acoustical implications of expanding onto the Mueller Property South. Reference sound-level emission levels for machinery proposed on-site were obtained through field measurements. Several scenarios were computer-modeled to create sound contours reflecting various future conditions. Noting that the acoustics will change as mining progresses on the subject property, modeling was performed to simulate several periods in the future which assumed extraction of 5%, 50%, 75%, and 100% of the reserves for the subject property. A three-dimensional terrain model considering pit depth, existing and proposed earthen berms, and proposed contours was used in the modeling to obtain a reasonable estimate of sound emissions, including dispersion and attenuation, throughout the project area. In addition to the excavation and processing noise emission assessment, a truck noise study was done to assess the egress and ingress routes relative to transporting sand and gravel northward to the processing area. While there are several options for transporting material out of the pit for processing (including existing access roads at East 96th Street, Gray Road, and East 106th Street), it was assumed for noise modeling purposes that the access drive from East 106th Street into Carmel Concrete would be used since it is in closest proximity to nearby residents. The Federal Highway Administration (FHWA) Traffic Noise Model (TNM 2.5) was used to model anticipated truck traffic along 106th Street and Hazel Dell Parkway. The results indicated little contribution to Kingswood and the park and are not considered impacted when compared with the Indiana Department of Transportation (INDOT) or FHWA noise prnicies. The results indicate that no facet of the proposed expansion onto Mueller Property South (sand and gravel) will create adverse acoustical conditions relative to existing sound levels on adjoining lands. Extraction elevations coupled with the terrain change and proposed berm construction/placement substantially attenuate the sound emitted on each property. Therefore, the modeling coupled with existing noise measurements indicate that the proposed expansion will not adversely affect the acoustical environment on adjacent lands. - 1 - o ~ D u a D a o D Q Q u D Q D D D D Source: USGS 7.5' Quadrangle, Fishers, Indiana Photorevised 1988 OWN BY: D.

A special use application was submitted for sand and gravel extraction on Mueller Property South. The property is located west of Hazel Dell Parkway and south of 106th Street. This report documents the results of a sound level study undertaken to determine the acoustical influence of the proposed expansion on the adjacent land uses. 2.1 GENERAL ENVIRONMENTAL ACOUSTICS PRINCIPLES Noise is defined as "unwanted sound." Therefore, it can be considered a psychological phenomenon and not a physical one. The roar of race cars adds to the excitement of spectators, and hence would be considered sound. This same roar may annoy nearby neighbors, thereby becoming noise. Factors playing a role in the perception of sound include magnitude, amplitude, duration, frequency, source, and receiver. Nevertheless, researchers have established a fair correlation between the measurement of sound, the A-weighted decibel (dBA), and its associated perceived human response. Figure 2.1 represents this correlation of qualitative and quantitative descriptions. The A-weighted scale refines the sound measurement unit of decibels to match the response of the human ear. It accounts for the fact that sounds of equal amplitude but different frequencies are not necessarily perceived to be equally loud. While the human ear can detect sounds from about 20 Hz to 20,000 Hz, it is more sensitive to frequencies between 500 and 4,000 Hz. To account for this occurrence, the A-weighted scale has been developed to place an emphasis on those frequencies which are more detectable to the human ear. The A-weighted scale, which has been in existence for over 40 years, is generally used in community and city noise ordinances and is expressed in units of dBA (decibels in the A-weighting). Because sound is actually an energy level, it must be recorded on a logarithmic scale and expressed in logarithmic units called decibels (dB). Given this scale, a doubling of a noise source will result in a 3-decibel increase in total level (Le., 50 dBA + 50 dBA = 53 dBA, not 100 dBA). Typically, a change in sound level between 2 and 3 dBA is barely perceptible, while a change of 5 dBA is readily noticeable by most people. A 1 O-dBA increase is usually perceived as a doubling - 3- D D D D o D D D D U ~ ~ U D U U D D D Sound Source Air Raid Siren Jack Hammer Thunder Emergency Sirens Rock Concert Chain Saw Lawn Mower Subway Yelling Normal Conversation Rainfall Refrigerator Whisper Sound Level .

Sound is also variable with the passage of time. When sound emission levels change (Le., volume increased or decreased) or source/receptor relationships change (Le., vehicle approaches and passes) over time, sound levels sensed at a given point can vary considerably. To account for this occurrence, several noise descriptors have been developed. The equivalent level or Leq is commonly used in community noise studies. The Leq is the constant, steady state sound level that, over a given period of time, would have the same acoustic energy as the actual varying level. In a sense, it is the average level, recognizing that the decibel is derived logarithmically. The Leq is reported for a given period of time, usually one hour, expressed Leq(h). 2.2 PROJECT DESCRIPTION Martin Marietta Materials, Inc. has proposed to expand its existing mining operations onto an adjacent tract of land to access known mineral reserves (referred to as the Mueller Property South). The special use application for Mueller Property South includes the extraction of sand and gravel. The site is located south of 106th Street, west of Hazel Dell Parkway in the City of Carmel, Clay Township, Hamilton County, Indiana (shown on Drawing 1.1). Mueller Property South: The sand and gravel operation on the Mueller Property South will be a dry operation using traditional mining equipment (front-end loader, excavator and trucks). To reach the sand and gravel, Martin Marietta must remove approximately five feet of topsoil and non-aggregate material known as "overbur- den." Overburden will be removed using earthmoving equipment such as pans, front-end loaders, etc. Martin Marietta plans for overburden removal to be completed during daylight hours (between one-half hour after sunrise and one-half hour before sunset) during the months of November through March (except as necessary to construct the visual and noise barrier described below) and only on days other than Saturday or Sunday. Removing overburden will expose approxi- mately 26 feet of sand and gravel. Due to the nature of the deposit and overburden depth, the bulk of the excavation will be conducted below the existing grade. There will be no aggregate processing on the subject property since sand and gravel processing will occur at the existing Carmel Sand Plant. The aggregate will be transported from the proposed pit north to 106th Street via an existing Martin Marietta access road. The trucks will proceed east on 106th Street, then north on Hazel Dell Parkway to access the existing Carmel Plant processing area. - 5 - o '-;0', "'D,',: ," ~! .'

The intent was to document current sound levels at adjacent residential areas (Kingswood Subdivision) associated with the Carmel Sand Plant and other ambient sounds. This facility is located in Carmel, Indiana, and is roughly bounded by the Hazel Dell Parkway to the east, East 106th Street to the south, the Kingswood Subdivision to the west, and Cool Creek to the north (see Drawing 1.1). Activity at the Carmel Sand Plant is concentrated on the southern half of the property (the northern half of the property being previously mined), with primary acoustic contributions coming from the crushing/ screening plant, truck activity, and front-end loaders. Additionally, the North Indianapolis Plant is located approximately one-half mile south of the Carmel Plant, but is far enough removed that it does not contribute to the acoustic environment near the Carmel Sand Plant. Noise measurements were taken on September 16, 2003, at 18 sites on both the existing Carmel Plant property as well as the northern section of the Mueller Property North. Additionally, five sites were located in the Kingswood Subdivision interior to determine sound levels in the community. Drawing 3.1 identifies the specific noise monitoring locations. Noise levels from these monitoring periods are reported in Table 3.1, Ambient Measurement Summary. Sites Berm 1 through Berm 14 were taken along the western edge of the Carmel Plant property line, directly adjacent to the Kingswood Subdivision. Sites Berm 1 through Berm 7 were located along the top of the existing earthen berm, while sites Berm 8 through Berm 14 were located behind the earthen berm adjacent to the Kingswood Subdivision property line. This grouping of sites provides a sample of the overall sound levels from the Carmel Plant at the residential property line, as well as a measure of the berms' attenuation. Measurements were primarily collected during plant operations, although Sites Berm 5 and Berm 12 were measured for a 24-hour duration to obtain nighttime and background noise levels. Comparison of the operating versus non-operating conditions highlights the contributions of the plant to the ambient sound levels. A second set of sites was placed along the southern boundary line of the Kingswood Subdivision. As with the previously defined "Berm" sites, data were collected during both operating and non-operating conditions. These sites are designated XP1 through XP4 on Drawing 3.1. -6- Illiiliililllliii.lIir ~'~' ,",<, ',' 'i" ':'/.it~ :l'f",Y:; =.:'.. <~Ji::''-j~;4 ':'=; . :"._~_ k Jti ,~:f .....~... .0: ;,.'...~'?t:::... -"; ,..~..-- ~ T' >~'~_!};:'>i"~ ~~ .

The measurements were taken when the plant was in operation although generally the plant was inaudible and sound levels were heavily influenced by typical ambient noises (local traffic, insect noise, lawn mowing etc.). All of the sites were monitored for a minimum of ten-minute intervals. Relevant monitoring standards (ANSI Standard S1.13-1995) were adhered to. The noise measurements were taken at each of the 18 locations with and without the influence of the operation of the Martin Marietta Materials Carmel Sand Plant. The location of the measurement sites was established to determine the current effectiveness of the existing earthen berm along the west side of the property, as well as document the existing sound levels. All sound levels are reported as Leq in decibels, using the A-weighted (dBA) scale. Additional information documented during the monitoring period included the identification of major noise sources and unusual noise events (Le., aircraft fly-bys, dogs barking, insect noise). Appendix A, Noise Monitoring Site Sketches, contains site-specific mapping and photographs. All monitoring was performed according to relevant standards using Metrosonics db-3080 sound analyzers. Calibration of the meters was performed with a Metrosonics cl-304 Calibrator. This equipment meets all standards of the American National Standard Specification for Sound Level Meters, ANSI S1.4-1983 (R1990). The "berm" monitoring sites are acoustically affected by contributions from the Carmel Sand Plant as well as background sounds (insect noise, rustling leaves, community noise, etc.). The combination of these two sources makes up the overall monitored level of these sites. While the Carmel Sand Plant influences certain sites on top of the berm, background sounds such as insects (Le., cicada noise, cricket noise) had a heavy influence for many of the "berm" sites due to the vegetation. The vegetation on the berm, combined with the season (Summer/Autumn) yielded insect noise which affected sound readings. Therefore, the noise levels presented in Table 3.1 are not solely due to the Carmel Sand Plant. The recorded sound levels at the "Berm" sites clearly indicate that the earthen berm does provide mitigation ranging from 2 to 9 dBA for plant noise. This is illustrated by comparing "Plant Operating" conditions for sites on top of the berm (Berm 1 through Berm 7) with sites behind the berm {Berm 8 through Berm 14). For instance, the operating sound levels for Berm 6 (63 dBA) and Berm 13 (55 dBA) yield an 8 dBA drop as a result of the berm. For reference, a 10 dBA reduction is perceived by the human ear as a halving of the sound level. The human ear has difficulty distinguishing a change in sound level of less than 3 dBA. - 9 - o o o o o o o o o o o o o o o o o o o The only area that does not appear to directly benefit from the earthen berm is located to the northwest of the facility. The sites in this region (Sites Berm 1,2,8, and 9) have relatively little influence from the plant; therefore, there is no reduction associated with the earthen berm. These sites are the farthest removed from the Carmel Sand Plant and therefore it is expected that the berm will provide less attenuation in this area. The sound levels recorded in the Kingswood Subdivision varied significantly depending on location, monitoring time period, and community activity. While sound readings were taken during the Camel Sand Plant operations, it was barely perceptible and essentially inaudible at these locations. Local traffic has a significant affect on the ambient sound levels, particularly in residential communities such as Kingswood Subdivision. Local sound levels can vary significantly depending on a neighbor's activities (lawn mowing), school bus traffic,local traffic, animals, insect noise, etc. The noise levels measured throughout Kingswood Subdivision during the daytime are typical for a residential subdivision (47 to 50 dBA). In addition, a measurement was repeated at Site BK3 at 4:00 A.M. on September 17, 2003, and yielded 43 dBA. Noise levels at Sites XP1 through XP4, taken along the southern boundary of the Kingswood Subdivision resulted in ambient sound levels ranging from 47 to 50 dBA. The Carmel Sand Plant does not influence the acoustics at these sites, and sound levels are primarily a result of ambient sounds including insect noise, cornfield rustling, etc. Site XP4 (61 dBA) was heavily influenced by activities at the adjacent Clay/Carmel Recreational Park. Long-term monitoring locations were also established to determining the evening ambient sound levels for comparison with future operational and truck noise. The proposal includes provisions to work until 10:00 P.M. in the evening; therefore, the existing ambient conditions were documented over a 24-hour period from 6:00 P.M. Monday, May 10, 2004, through 11 :00 A.M., Wednesday, May 12, 2004. Sites Berm 5 and Berm 12 were selected for long-term measure- ments. The data are presented in graphical format on Figure 3.1. The results are typical for a suburban neighborhood, the sound levels decrease as human activity (traffic, etc.) increases. - 10 - D Sound level leq(h) in dBA D f\) w w .j:>.. .j:>.. 01 01 en 01 0 01 0 01 ~ 01 0 0 0 0 0 0 0 0 0 D ~ 6:00:00 PM i 0 7:00:00 PM I ~ 0.. i f\)l3l 8:00:00 PM i D 0:< I ~~ 9:00:00 PM i. l3l I ,~"; '< 10:00:00 PM I .0 11 :00:00 PM D 12:00:00 AM I I 1 :00:00 AM I 2:00:00 AM I 0 I 3:00:00 AM i i. 4:00:00 AM r D 5:00:00 AM I I I 6:00:00 AM i i 7:00:00 AM I :n n I -l 8:00:00 AM I G) c I c: CD 9:00:00 AM i (Jl JJ 0.. i l3l 10:00:00 AM I m 0 :< .- I w ~ 11 :00:00 AM I ...... l3l 12:00:00 PM I I\) '< ...... 01::0 D -I ...... 1 :00:00 PM ::I: .

The proposed expansion involves using existing processing areas at adjacent facilities and does not include provisions to process extracted material on the Mueller property. Generally, the processing (crushing, screening, conveying, loading of material) operations have the greatest potential to adversely affect the acoustical environment. Since this special use application does not include the installation and subsequent operation of a processing facility, the anticipated effect to the local acoustical environment is minimal. The existing processing facility at the Carmel Sand Plant will continue to serve as the processing facility for this expansion area. Therefore, the noise analysis was focused on the extraction techniques and their associated implications to the acoustical environment. The goal of the study was to determine the acoustical implications associated with the extraction and transport of material from the Mueller Property South. Noting that the acoustics will change as mining progresses on the property, future estimates were made for several scenarios based on the operations' development (25%, 50%, 75%, and 100% extraction) of the entire property. In addition, a truck noise study was performed using INDOT methodology to assess the proposed transport of material to the processing area. 4.1 METHODOLOGY Extraction/Processi ng The future acoustical environment was assessed using the proposed extraction equipment sound emissions coupled with an Environmental Noise Model v. 3.06 (ENM). The emission rates used in the model were derived directly from noise measurements obtained at Carmel Sand Plant, North Indianapolis Plant, and Franklin Sand and Gravel. ENM was used to simulate the acoustical environment of the proposed mining operations for the Mueller Property. This program is modular in that the user inputs topographical data, source data, and receptor data separately. The model then uses each individual module to predict the future sound environment. A three-dimensional topographical model (encompassing approximately one square mile) was created for importation into ENM. Ground elevations and rontours were obtained from base - 12 - o o o o o o o o o o o o o o o o o o o topographic mapping. Existing ground level contours and existing topography along with proposed extraction elevations were incorporated into the model. The noise modeling topography was compiled for the Mueller Property for several periods in the future based on the progress of extraction. For example, the topography (and associated acoustical effects) will change as the operations progress. The location of extraction equipment will change, as well as the terrain of the sand pit, altering the acoustical environment. Estimates were made for the Mueller property based on four scenarios - 5% of property mined, 50% of property mined, 75% of property mined, and full extraction (100%). All of the proposed and existing berms were incorporated into the model. The height of most proposed berms varies from six to ten feet, although the berm located to the north of the Mueller Property South, parallel to East 106th Street, is considerably higher (approximately 20 feet). Ground zones, representing typical ground cover, were input based on field reconnaissance and project mapping. Noise sources and their emissions were derived by taking measurements of anticipated extraction techniques on each property. Measurements were taken at specified distances under full throttle conditions to calculate sound power levels for use in ENM program. The sand and gravel extraction equipment proposed for the Mueller Property South was measured to determine sound emissions for importation into ENM. A CAT 9888 Loader was measured under full throttle while dumping material into a transfer hopper, and the resulting sound power level was used to estimate the Mueller Property South sand and gravel extraction. Acoustical measurement data as obtained in the field are contained in Appendix A. In addition to the modeling for the Mueller Property South noise source(s), several other facets of the existing acoustical environment were included in the modeling. The emissions from the existing Carmel Sand Plant were estimated based on 1/1 octave measurements taken on September 17, 2003. The processing plant contributes slightly to the noise levels measured along the western boundary earthen berm (Table 3.1); therefore, it was included to obtain a cumulative sound level estimate (Mueller Property expansion plus processing plant). ENM is capable of either predicting maximum A-Weighted sound levels at discrete receptors (single locations) or calculating sound contours given three-dimensional terrain. Due to the number of extraction scenarios, contour modeling was used to display many of the operating scenarios. The model generates a network of receivers over the terrain and estimates the acoustical environment for an entire region. Each scenario was modeled based on four future conditions (extraction progress: 5% of property mined, 50% of property mined, 75% of property mined, and 100% extraction).

ENM model details are located in Appendix B. The sound level contouring presented in Drawing 4.1 was generated in ENM based on proposed noise sources contained within Mueller Property South. While these illustrations include the major noise sources, local background sources, traffic, wind, and human activity will also affect the acoustical environment and are not modeled. The lower limit of the contours was set at 50 dBA, representing the measured background levels (typical for residential areas). While the contouring indicates that a region is 50 dBA or below, existing background noise sources not associated with mining in these areas may dominate and locally elevate sound levels above 50 dBA. The sand and gravel operation for Mueller Property South will be extracted through dry mining techniques. Removing overburden will expose approximately 26 feet of the sand and gravel. Martin Marietta will use typical mining equipment such as front-end loaders, excavators, and dump trucks to remove the sand and gravel. A three-dimensional model of the sand and gravel pit was created for several scenarios, using actual pit elevations and loader operating locations. The results indicate that the equipment operation or transport of material off-site will not have any effect on sound levels outside the property. Drawing 4.1 displays the noise contours for the Mueller Property South Sand and Gravel Operation for several operation scenarios. The ENM contouring indicates the equipment noise dissipates quickly (notice tight contour pattern) primarily as a result of the pit depth, although the proposed adjacent earth berm bordering the north of the property provides some attenuation during the onset of extraction. Transport from Mueller South to Processing Plant The transport of material from the proposed extraction site to the existing processing plant will be conducted using dump trucks. While there are several options for transporting material out of the pit for processing (including existing access roads at East 96th Street, Gray Road, and East 106th Street), it was assumed for noise modeling purposes that the access drive from East 106th Street into Carmel Concrete would be used since it is in closest proximity to nearby residents. This existing access road is located immediately west of the proposed site. A truck noise study was conducted to assess the potential acoustical implications on the surrounding noise-sensitive land uses. The FHW A methodology was used to predict hourly sound levels with and without the trucks operating. FHWA's TNM 2.5 was used to model sound levels for comparison with Indiana Department of Transportation (INDOT) noise policy. INDOT policy indicates a traffic noise impact - 15 - o o o o o o o o o o o o 10 i o o o o o o if the sound level is increased 15 dBA over the existing conditions or if the absolute level is over 66 dBA [Leq(h) in dBA]. A three-dimensional TNM 2.5 computer model was created for the local roadway network (e.g., 106th Street, Hazel Dell Parkway, Mueller South egress/ingress). Truck acceleration/ deceleration was accounted for in TNM using the program's speed constraint functions. Two scenarios were modeled to assess the acoustical environment with and without the trucks. FHWA and INDOT policies require the use of the hourly L-equivalent (Leq) to assess the cumulative effects over a one-hour period. An estimate was made relative to the maximum number of trucks accessing the proposed Mueller Sand and Gravel Property per hour (32 truck trips/hour) during evening hours (6:00 to 10:00 P.M.). This analysis focused on evening hours as a worst-case (Le., ambient levels are lower during the evening, increasing the potential for the proposed truck traffic to influence the acoustical environment). The truck trip estimate was used to predict the maximum hourly Leq (essentially the hourly average) for the Clay/Carmel Park vicinity as well as locations to the south of the Kingswood Development (Sites XP1 through XP4). Traffic on 106th Street and Hazel Dell Parkway was derived from counts taken during the baseline monitoring events (4:00 P.M. weekday hour). One TNM 2.5 run was completed with only "background" traffic volumes as counted in the field during the noise monitoring. The predicted hourly Leq was assumed to be the influence from local traffic on 106th Street and Hazel Dell Parkway. These predictions were slightly lower than the measured volumes for the receptors along the southern edge of the Kingswood Development (Sites XP1 through XP4), indicating influence from other background sources (Le., insects, leaves rustling, etc.). Generally, traffic on 106th Street currently has little influence on the sound levels in this region. A second TNM 2.5 run was created by adding the proposed truck volumes from the Mueller operation onto the existing traffic network. The results are presented in Table 4.1. Adding this proposed truck traffic increases the sound level in the model by 4-8 dBA, but even this predicted sound level remains below existing ambient background levels. Sound level contributions from the truck volumes on local roads were modeled to be 43-45 dBA in the southern end of Kingswood and 50 dBA at the Carmel/Clay Park. These are below ambient background levels, indicating that background sources will continue to dominate these locations and will exceed noise levels from the mining truck traffic. In addition, these levels are low when compared to the FHWA criteria for highway noise impacts (e.g., 66 dBA). - 16 - o o o o o o o o o o o o o o o o o o o In summary, the truck route from Mueller Property South does not influence background levels nor would it exceed typical noise impact criteria for highway generated noise (Le., FHW A, INDOT). Traffic on 106th Street currently has little influence on sound levels in the region, a trend that will continue in the future after Mueller South is in operation.

Skelly and Loy performed a baseline sound study to determine existing conditions in the area and to assess the potential for increased sound levels as a result of the proposed expansion. Noise monitoring was performed to determine contributions from existing operations to the local acoustical environment, and reference data were gathered from various operations to determine proposed sound-level emissions. Computer noise modeling was performed using ENM and FHWA's TNM 2.5 Traffic Noise Model, and noise contours were examined for several proposed operation scenarios. The results indicate that no facet of the proposed expansion will create adverse acoustical conditions relative to existing sound levels. Based on modeling results, the noise drops off quickly due to pit depth and berm configuration. Therefore, the proposed expansion will not adversely affect the acoustical environment outside the property. - 18 - U: 0:' ~J '0 ,- :.;' . ~: 8 -:0' -', ,;~ . y ;~ ( ~ _.~, D,c., , " '.

Acoustics - the science or study of sound. Acoustic Trauma - the physical destruction of the inner ear hearing organs resulting from exposure to peak sound pressure levels greater than 140 dB. Acoustic trauma normally results in permanent hearing loss. Active Noise Control - the cancellation of sound waves by introducing a minor impact (1800 out of phase) of the original sound wave to the sound path. Ambient Noise Level- the total noise level in the acoustic environment, usually including the noise source of interest.
