Stabilized Biosolids for Quarry Reclamation – Demonstration Project “ a project that combines Industrial Waste with Human Waste to produce a beneficial product that can be used to reclaim exhausted rock quarries” Presented by: M.D. Of Bighorn Hugh Pettigrew C.E.T Director of Operations

1. Stabilized Biosolids for Quarry
Reclamation – Demonstration Project
“ a project that combines Industrial Waste with
Human Waste to produce a beneficial product that
can be used to reclaim exhausted rock quarries”
Part 1- The Municipal Perspective
Presented by:
M.D. Of Bighorn
Hugh Pettigrew C.E.T
Director of Operations

2. Project Backgrounder
The M.D. of Bighorn is a relatively new Alberta Municipality
having been incorporated in 1988. It is a rural Municipality
of approximately 2600 square kilometers.
The area is diverse and contains mixed zoning/uses of
Residential, Commercial, Industrial, Agricultural and
Recreational entities. Our Population is just under 1,400
soles.
The MD is a full partner in the Bow Valley Waste
Management Commission (B.V.W.M.C) along with
The Town of Banff and the Town of Canmore

4. Project Backgrounder (Cont)
Because Bighorn is growing rapidly and that we are now Planning
NEW Mechanical Waste Water Treatment Plant Facilities (WWTP) in
a number of Hamlets.
In other words:
The MD will soon need to treat and dispose of “ Biosolids “ from
those facilities on a daily basis.

5.  So what are BIOSOLIDS?????
 The term biosolids was formally recognized in 1991 by the Water
Environment Federation (WEF). The WEF, founded in 1928, is a not-for-
profit technical and educational organization with Wastewater treatment
operators and engineers as members involved in aspects of the global water
environment.
 " Biosolids is the term created in 1991 by the Name Change Task Force at
WEF to differentiate raw, untreated sewage sludge from treated and tested
sewage sludge that can legally be utilized as soil amendment and fertilizer.
 The Federation newsletter published a request for alternative names.
Members sent in over 250 suggestions, including "all growth,"
"purenutri," "biolife," "bioslurp," "black gold," "geoslime," "sca-
doo," "the end product," "humanure," "hu-doo," "organic
residuals," "bioresidue," "urban biomass," "powergro," "organite,"
"recyclite," "nutri-cake" and "ROSE," short for "recycling of solids
environmentally."[4] In June 1991, the Name Change Task Force finally
settled on "biosolids," which it defined as the "nutrient-rich, organic
byproduct of the nation's wastewater treatment process."

6. Options
 So what are our options for managing these Biosolids?
 1) Should we build a Composting Facility- In vessel?
 Or
 2) Should we Transport our Sludge ( > 100 KM)
 to an approved site as an Agriculture Land application
 Any Other?

7. What Do We Know!
First- We have a lime plant in our area-
Secondly-
We have Lime kiln dust (LKD) going to a landfill...+/-7,000 T per year
Third-
someone has to reclaim all those quarries - right here in our backyard !
99 years worth!
Fourth-
We got POOP!

8. Eureka!
As per Victor Hugo’s famous quote:
"There is nothing more powerful than an idea whose time
has come."
Lime Stabilization!

9. Where did that Idea came from?
Started by a BCEC recommendation in 2003
•BVWMC study/2cg report in 2004
“ Lime has been used for over 100 years to chemically stabilize
and reduce odors from biological waste”
excerpt from 2 cg report
•Visited the Lake Louise WWTP ( 2005)

10. Setting Up The Pilot
 April 2006
• Met with Graymont
• Addressed political
• Partnerships agreements
 May 2006 to June 2007
• Pilot sitting details and Technical reviews

11. We get APPROVAL!
 September 2007
a) “ Re:Municipal District of Bighorn No. 8 Dead
Man’s Flats Class I Wastewater Treatment Plant
Sludge Disposal Authorization EPEA Approval No.
593-01-00”
b) “We have no objection to you proceeding with
your Biosolids Alkaline Stabilization Pilot Project
as described in your proposal, but we remind you
of your obligation to comply with the general
provisions of the EPEA and the associated
regulations”

12. THE TEST
SITE
DEAD MANS
FLATS

13. Site preparation- Fall 2007
 MD staff prepared the site
• Placed Sand and Liner
• Installed protection Fencing
• Provided “On site” facilities
 Graymont Staff installed:
• Tub Mixer
• Bagging and conveying
equipment
• Technical expertise
• Electrical

14. Phase 1 Pilot Schedule
 Met in spring of 2008
 Graymont’s staff then
Re-Tested & calibrated
equipment
 MD -organized sludge
delivery (trucking)
 Included Sludge from
Town of Banff and
Canmore.

15. PILOT TAKES PLACE
Successful Start :
June 4,5 and 6th
Treated 35 M3 of sludge
Sent samples for Lab tests

18. What did we want from this?
 The MD wants:
• Cost effective solution
• Sustainability !
• A product that is free of pathogens, coliforms and
meets CCME Guidelines for Class A
• A product that can be used in the viscinity.
 The Industry wants:
• A market for their waste by-product LKD
• Sustainability !
• Need reclamation soil for their quarries
“ We want to treat Industrial waste with Human waste” P.Ryan

19. What did we get?

20. Stabilization Implementation
Estimates
 The Pilot costs to the MD was less
than $10,000 plus Large in kind
contributions from Graymont
( equipment , LKD and expertise)
 The Capitalization & Operational
Costs are estimated to be very
effective and much less than other
methods.

21. Really Now
What’s Next
 Continue and invest in a Product analysis
-How good of a soil is this…..
 Apply and Obtain Alberta Environment (Aenv)
and Alberta Sustainable Resource Department
(SRD) approvals for our stabilized biosolids
land application-
 Pilot an actual Reclamation Site
