Sleeman Breweries

Sleemen Brewery

Location: Guelph, Ontario, Canada
Owner/Operator: Sleeman Breweries Ltd.

With a presence in Guelph, Ontario since 1851, Sleeman Breweries is the third largest brewing company in Canada. Established in 1988, the current brewery produces 10 brands of beer enjoyed the world over.

Sleeman Breweries retained HGC Engineering to undertake an Acoustic Assessment of their Guelph facility.  The study was required in support of an application to the Ministry of Environment (MOE) for a Certificate of Approval (Air & Noise).

The purpose of the assessment was to evaluate the overall sound emissions of the facility under a predictable worst case operating scenario, which is defined as an hour when typically busy operation of the stationary sources under consideration could coincide with an hour of low background sound.

Source sound level measurements were conducted at the facility and the source sound levels were used as input to a predictive acoustical model to quantify the environmental sound emissions associated with the facility. Acoustic assessment criteria were established in accordance with the sound level limits in MOE guideline NPC-205 and used to assess the sound emissions of the facility.

The Sleeman Brewery operation is comprised of two buildings. The larger of the two buildings houses all production activities and offices, while the smaller building is used for warehousing. The facility produces beer, starting with grains and corn syrup, which are brought to the facility in tractor trailers.  The finished product after brewing is then bottled, canned or kegged, and is shipped by truck from the docks at the northwest end of the north facility.

Brewing operations at the facility occur 24 hours per day, seven days per week, while packaging operations occur 24 hours per day, six days per week.

The measurements and analysis indicated that the sound emissions of the facility were within applicable sound level limits, as set out in MOE publication NPC-205.

Primary sound sources at the facility that were evaluated:

  • Process Exhausts
  • Building Ventilation & HVAC
  • Cooling Towers & Condensers
  • Emergency Diesel Generator
  • Trucking (malt, spent grain, spent yeast, corn syrup, hops, CO2, finished product)

Acoustical Engineering Services Included:

  • Comprehensive onsite and offsite acoustical measurements
  • Predictive acoustical modeling
