Noise Remediation Plan

• Introduction
• Shire contracted R.G. Vanderweil Engineers (RGV)
  to investigate noise concerns at GHT B300 located
  at 300 Patriot Way, Lexington, MA. These noise
  concerns were raised by the abutters located on
  Shade St. and reported to Patriot Partners, who
  in turn contracted a consultant specializing in
  acoustic analysis testing to investigate the
  issue. This study isolated HGT B300 as the
  likely source of the noise concern raised by
  abutters. The purpose of this study is to
  support Shires evaluation of the likely
  contributor to this concern and to identify an
  appropriate path forward to mitigate it.
•  
• Approach
• Shire, RGV, TRG and Acentech met initially to
  discuss the approach to identify the most
  significant contributor to the noise concern
  raised by the abutters on Shade St. and to
  present options to solve this issue. A physical
  survey to document the exact location and
  installation of the rooftop exhaust fans was
  required for the acoustical model. This was
  followed by night time acoustical testing of
  these exhaust fans. A review of options based on
  the overall mitigation effectiveness of each was
  conducted.
•  
• Physical Survey
• RGV and Shire surveyed the rooftop equipment and
  verified the existing layout based on drawings
  provided by Shire. Shire obtained equipment cuts
  sheets of noise generating rooftop equipment.
  During the survey the reported noise from the
  exhaust fans was reconfirmed as the primary
  contributor for the facility.

Noise Remediation Plan

• Acoustic Testing
• The team (RGV, Shire and Acentech) visited Shire
  HGT B300 to conduct acoustical testing of the
  laboratory exhaust fans. Readings were taken via
  Rion model NA-28 sound level meters, two
  hand-held to measure in the immediate proximity
  of specific pieces of equipment and two mounted
  meters located in the Shire HGT300 parking lot
  and at the property line by the woods at Shade
  Street. Data taken from that evening was then
  analyzed and options were presented to the team
  through acoustical model analysis.
• Recommendation
• Based on the field survey and review of the
  physical installation, acoustical measurements,
  computer model, two (2) options are recommended
  to reduce the noise emitted from the laboratory
  exhaust fans.
•  
• 1. Provide a bypass silencer and discharge
  silencer on each of the Lab Exhaust Fans This
  option will attenuate the noise generated by the
  bypass fan inlet which is open to atmosphere at
  the bottom of the fan set and attenuate the sound
  generated at the top of each fan where the air is
  discharged to the atmosphere.
•  
• 2. Barrier in front of the Lab Exhaust Fans (LEF
  6.1, 6.2, 6.3)
• Extend the existing barrier in elevation in front
  of the Lab Exhaust Fans (LEF 6.1, 6.2, 6.3) so
  that it is 2 0 above at the level of the Lab
  Exhaust Fan discharge. This will run the East
  face of the existing barrier wall from column X15
  to X21 and along the North facing barrier from
  column XM to XK.
• Each option is described individually but by
  implementing them together, the level of noise
  reduction will be enhanced.

Noise Remediation Plan

• Estimated Cost Schedule
• Option 1 Exhaust Fan Attenuators
• Install sound attenuators on bypass and
  discharge of each fan (3)

  the fans (with the new sound attenuators)
• Budget Cost 206,000
• Schedule 19 weeks after release of Engineering

Fiscal Benefits for Lexington

• Approximately 2.2 million in new net annual tax
  revenue
• Approximately 2.5 million in new gross annual
  tax revenue
• Existing approved and ongoing construction at LTP
  will generate 2.5 million in gross annual
  property taxes at full build out.
• Therefore, LTP will generate approximately 5
  million in annual tax revenues if the current
  proposal is approved.
• Cost to revenue ratio of .13 at project
  stabilization. 87 cents of every revenue dollar
  will accrue as a net fiscal benefit.
• Expand Towns total assessed commercial valuation
  by approximately 100 million
• Project will generate approximately 1,500,000 in
  construction related permit fees during build-out
