Little Current Lagoon Capacity Expansion
Schedule C Class Environmental Assessment
Environmental Study Report (ESR) Addendum
Introduction
The Town of Northeastern Manitoulin and the Islands (Town) is proposing to undertake
upgrades to the Little Current sewage treatment lagoons to provide increased treatment
capacity and improved effluent quality. The environmental study report for the project was
completed by Stantec Consulting Ltd. and placed on public record in January 2011; however,
project implementation was delayed due to funding constraints. Since that time, flows to the
sewage system have continued to increase and the system is now operating at an estimated
45% over its original design capacity. In 2017, The Greer Galloway Group was engaged to
complete the detailed design and tendering for the first phase of the lagoon expansion.
Updated sewage flow projections, and revised effluent criteria developed in conjunction with
the Ministry of the Environment and Climate Change (MOECC), combined with higher than
anticipated costs due to challenging site conditions, have resulted in changes to the design
concept presented in the ESR to accomplish the preferred solution. The purpose of this
addendum is to document the proposed design changes and discuss any potential
environmental implications relative to those presented in the original environmental study
report.
Existing Lagoon
The existing 3‐cell facultative lagoon system serving the community of Little Current is designed
to treat average daily sewage flows of 927 m3/day, discharging seasonally in spring and fall
(over discharge periods of 3 to 4 weeks) through a municipal drainage ditch that flows through
pasture lands for approximately 3 km before entering Strawberry Creek and ultimately
Strawberry Channel of Lake Huron. Sanitary flows over the past 5 years (1,344 m3/day on
average) have exceeded this capacity, leading to earlier than anticipated spring discharges.
Updated Design Flow
An updated design flow target of 1,500 m3/day was established based on recent sanitary flows
(1,344 m3/day average over the past 5 years) and population statistics. This is 36% higher than
the 1,100 m3/day design flow specified in the ESR, despite a similar population growth
assumption of 11 persons per year over the next 20 years. Detailed calculations are contained
in Technical Memorandum #1 (see Appendix A).

Revised Effluent Criteria
Based on input provided by the MOECC, revised effluent criteria (presented in Table 1 below)
were developed for the Little Current Lagoon.
Since the lagoon effluent is discharged through a municipal ditch that flows over pasture land
where it is exposed to waste products from grazing cattle before it reaches Strawberry Creek, it
was agreed that the more stringent effluent requirements recommended in the ESR are not
necessary and standard F‐5 guidelines are sufficient (refer to Jan. 12, 2018 memo from MOECC
Surface Water Specialist in Appendix B). The ammonia and toxicity testing requirements were
also removed.

Preferred Solution and Review of Design Concepts in ESR
The environmental study report identified the need for lagoon upgrades to provide increased
treatment capacity for future growth and development, and to meet MOECC effluent quality
standards.
The preferred solution was to “Upgrade Existing Lagoons with New Technology to Increase
Capacity”. The ESR presented the following two preferred design concepts, suggesting that the
final selection be made during the detailed design phase based on a more detailed cost
analysis. Both concepts involve utilizing the existing lagoon cells with additional treatment
processes, discharging effluent to the existing drainage channel over an extended discharge
period.
1. Intermittent Sand Filtration (ISF) ‐ ISF Technology involves intermittent application of
lagoon effluent onto the surface of a sand filter bed to provide increased ammonia
removal and effluent polishing through a combination of physical straining and
biochemical processes. An ISF system would allow effluent to be discharged over an
extended period of 6 months (typically April ‐ October) when temperatures are warm
enough to permit effective operation. An additional lagoon cell would need to be
Town of Northeastern Manitoulin and the Islands 3 Little Current Lagoon Capacity Expansion Class EA ‐ Addendum to ESR
July 10, 2018
constructed on the adjacent Town land to provide 6 months storage capacity for the
winter months when the system would not be operational. This option was pursued
initially since it provided the opportunity for phased implementation to obtain an
immediate benefit from increased storage capacity while deferring the cost of the ISF to
a future upgrade. However, preliminary investigations and geotechnical work revealed
that the costs related to this approach would be significantly higher than originally
expected given the increased design flows and challenging site conditions.
2. Submerged Attached Growth Reactor (SAGR) ‐ SAGR systems are primarily used for
ammonia removal and feature aerated coarse gravel beds that provide an environment
for target bacteria to reside. Unlike ISF, SAGR systems operate effectively in cold
temperatures, allowing continuous effluent discharge year‐round. According to the ESR,
this option would involve modifications to existing lagoon cells (e.g. reconfiguring flows
and adding mechanical aeration) as well as construction of new SAGR cells downstream
of the existing cells, possibly expanding onto the adjacent land. Given that the revised
effluent criteria do not include ammonia requirements, a SAGR system may no longer
be required (refer to supporting email correspondence with MOECC in Appendix B).
Proposed Design
Based on the updated design flows, effluent criteria and additional information obtained during
the design phase, both preferred design concepts (ISF and SAGR) were determined to be cost‐
prohibitive. A new design concept was developed to implement the preferred solution in a
more cost‐effective manner. It retains the following previously accepted features of the ISF/
SAGR designs:
Utilizes existing lagoon cells (ISF, SAGR)
Continuous discharge of treated effluent (SAGR)
Construction of an additional cell on adjacent Town land west of the existing lagoon (ISF,
SAGR)
Continuous chemical addition system for enhanced phosphorus removal (ISF, SAGR)
New utility building to house blowers for mechanical aeration (SAGR)
The existing three facultative lagoon cells will continue to be utilized for cBOD and TSS removal.
To support the change from seasonal to continuous discharge, several modifications and
enhancements are also proposed:
The existing flow path through the lagoon will be reconfigured by modifying interconnecting
pipes to promote series flow through the system during normal operations while providing
flexibility to bypass cells for maintenance. Baffle curtains will also be added to individual cells to
minimize short‐circuiting.
Town of Northeastern Manitoulin and the Islands 4 Little Current Lagoon Capacity Expansion Class EA ‐ Addendum to ESR
July 10, 2018
A new chemical feed system and bulk storage tank will be added to provide continuous ferric
sulfate dosing between lagoon Cells 1 and 2 for enhanced phosphorous removal.
A new, smaller post‐aeration polishing cell will be added downstream of the existing lagoon
cells for removal of hydrogen sulfide (H2S) that forms under ice cover during cold temperatures.
This additional treatment reduces the potential for odour problems associated with continuous
effluent discharge during winter. A new utility building will be constructed to house the blowers
required for aeration as well as the pumping equipment for the chemical feed system.
Additional details concerning the proposed design are provided in Appendix C.
Environmental Impacts
Environmental impacts of the proposed design are generally similar to those presented in the
ESR.
Reconfiguring the existing lagoons for continuous effluent discharge reduces the potential for
downstream flooding during wet weather and benefits downstream environments. Additional
treatment for removal of hydrogen sulfide reduces the potential for odour problems during
winter operations.
The proposed design allows for increased treatment capacity with a reduced footprint and less
land disturbance than the ISF system previously accepted as a preferred design. Temporary
impacts during construction are also expected to be reduced since the new design requires
significantly less excavation to construct the smaller post‐aeration cell. Standard mitigating
measures outlined in the ESR will apply.
The new design concept accomplishes the preferred solution, providing increased treatment
capacity for future growth while meeting effluent requirements established in conjunction with
the MOECC. Estimated construction costs for the new design are significantly lower than those
presented in the ESR ($1.0M ‐1.5M compared with $2.4M ‐ $3.5M) despite the fact that the
design flows have increased by more than 35%.
Public and Agency Consultation
The Municipal Class Environmental Assessment process (October 2000, as amended) for
Schedule C projects requires that any project modifications which occur after the filing of the
Environmental Study Report be reviewed and documented in an addendum to the ESR
describing the circumstances necessitating the change, the environmental implications of the
change, and mitigating measures for any negative environmental effects.
As noted previously, extensive additional consultation was undertaken with the MOECC
regarding effluent requirements and enhanced treatment options to develop the basis for the

new proposed design, which accomplishes the preferred solution documented in the ESR with
no anticipated additional environmental impacts.
The project contact list and record of correspondence is contained in Appendix D.
Notice of Filing of Addendum
The Notice of Filing of Addendum was published on July 10, 2018 on the Town of Northeastern
Manitoulin and the Islands website and also in local newspapers. This Addendum is now
available for the required 30‐day comment period. Only the changes proposed in the

April 4th, 2018 Town of Northeastern Manitoulin and the Islands (NEMI) 14 Water Street East PO Box 608 Little Current, Ontario P0P 1K0 Attn: Dave Williamson, CAO Re: Little Current Lagoon Expansion Technical Memorandum # 1 GGG Project#: 17-3-7636 Mr. Williamson, As part of the Environmental Study Report (ESR) for the Little Current Lagoon Expansion, this Technical Memorandum (TM) is presented to outline updated flow projection requirements. Background: The population of the Town of NEMI recorded by Statistics Canada during the 2016 Census is 2712 people. The most populous community is Little Current with population of 1558 as of the 2016 Census. The remaining population is distributed throughout the rural areas and small communities including islands in Lake Huron. There are no major industries in the community of Little Current, but the community serves as a support services centre for NEMI. Little Current is home to municipal and federal government services, a hospital and long-term healthcare facility, financial services, police services, school board offices, a primary school and various commercial services. Wastewater treatment at Little Current is a 3-cell lagoon system located at rural address 277 Highway 540, District of Manitoulin. Facultative lagoons have provided the community of Little Current with sanitary treatment for more than thirty years. Operation of the system is authorized under the Ministry of Environment and Climate Change (MOECC) Provisional Certificate of Approval. Objectives and guidelines for the quality of discharged treated effluent are set out for the treatment system by the MOECC. The Little Current water treatment plant (WTP) draws its raw water from the North Channel in Lake Huron. The treated water is distributed to the community of Little Current. Ontario Clean Water Agency (OCWA) operators state the average production of finished drinking water is 1000 m3/day to mostly residential consumers. Large volume non-residential consumers include the local hospital and the Coldwater Fisheries Inc. fish processing and packaging plant.

The existing system has a 180-day storage capacity of 166,860 m3 and a design average daily raw sewage flow rating of 927 m3/day, which is currently at 45 percent overcapacity. As such, the wastewater treatment facility is currently operating beyond its design hydraulic capacity. In addition, Little Current requires treatment capacity to accommodate future growth.
Forecasted Population & Sewage Flows The forecasted sewage flows for Little Current were estimated based on historical and current sewage flow rates, as well as current and forecasted population growth. Based on the current operating conditions, the system can benefit from an increased capacity to accommodate further growth in community and infrastructure, and to avoid potential lagoon overflows or out-of-season discharges that can negatively impact the nearby environment.
An examination of sixty-month flow data found the average daily flow to be 1344 m3/day – approximately 45% beyond the current rated capacity (see Appendix A for monthly flows by year). Please note that the December 2016 flow data was significantly low and is considered to be a flow meter error. Therefore, a five-year average was calculated to replace the anomaly.
• (1338 + 1328 + 1484 + 1178 + 1391) ÷ 5 = 1344 m3/day The current serviced population was established by using 2016 Census data gathered from Statistics Canada. Based on the 2010 ESR, population will grow by 11 persons per year (5 lots per year; 2.2 persons per lot). The flow per capita per day (including infiltration) as of 2017 was then established by dividing the existing average daily flow rate by 2016 Census population plus the growth of 11 persons per the 2010 ESR.
• (1344 m3/day) ÷ 1558 + 11 people = 857 L/capita/day The per capita per day calculation rate is considered high compared to standard average high ranges of 450 L/capita/day according to the 2008 MOECC Design Guidelines for Sewage Works. Such high volumes of raw sewage per capita can indicate high extraneous infiltration (I&I) in the collection system at Little Current. Significant work has been undertaken by the Town to correct this issue of the years, however the flows continue to exceed averages for the province. Although the Town will continue with an I&I program, they must provide hydraulic capacity to treat the flows they continue to experience. Based on the 2010 ESR, population will grow by 11 persons per year (5 lots per year; 2.2 persons per lot). By leveraging the 2016 Census data and the 2010 ESR growth ratio, we can presume that the total population of Little Current will be 1789 by 2037.
• 1569 + (11 persons x 20 years) = 1789 people Based on the 2010 growth ratio, using 2016 Census data with a 20-year growth horizon, and updated with the current average daily flow per capita, the capacity requirement is calculated below:
• 1789 people x 857 L/capita/day = 1533 m3/d

Conclusion/Discussion At the recent sixty-month average flow rate of 1344 m3/day, the Little Current sewage lagoons treatment system is at 45 percent overcapacity and requires immediate expansion of treatment capacity to meet near-term base growth in serviced areas of the community. Upgrading the existing lagoons due to the current overcapacity of the treatment system, it is recommended that the target design flow should be considered to 1500 m3/day. This will provide sufficient capacity to treat current flows as well as providing capacity for modest future population growth. If you have any questions or concerns, please contact the undersigned.

January 12th 2018 M E M O R A N D U M TO: Parise Drolet, Senior Environmental Officer, Sudbury District FROM: Rod Sein, Surface Water Specialist, Northern Region RE: Little Current Lagoons Proposed Effluent Criteria This memo addresses the December 22, 2017 letter from Tony Guerrera, Greer Galloway Consulting Engineers regarding the proposed effluent criteria for the Little Current Wastewater Lagoons. We all met on November 2nd to discuss what is expected regarding the upgrade of the lagoons. It was proposed that the lagoons change from seasonal discharge to continuous discharge as an option for handling both current insufficient capacity and future increased flow rates. In addition, options for enhanced treatment of the effluent were discussed. Background The existing the cell lagoon system currently discharges to the environment on a seasonal basis (spring/fall). Insufficient capacity has resulted in earlier than anticipated discharges. This and concern over future capacity requirements dictated the need for, and the completion of, a Class Environmental Assessment (completed 2010). The EA recommended upgrading the existing lagoons with new technology in order to meet future expansion. During the EA process (2009-2010) I provided surface water support for the file and worked closely with the previous consultant (Stantec). I have visited the site on numerous occasions. Receiving waters The effluent from the lagoon system discharges into a municipal drain system that was constructed in the 1960’s to convey lagoon drainage. Thus, it is not a natural surface water feature. The drainage ditch system flows south of the lagoon, crosses Morpeth
1
side road, follows ditches on the west side of highway 6 then crosses through un-fenced pasture land. The effluent eventually enters Strawberry Creek, a distance of approximately 3km from the lagoon, prior to discharging to the Strawberry Channel, Lake Huron. Strawberry Creek represents the first downstream natural surface water body. As the effluent travels from the lagoons, it is exposed to waste products (urine, faecal matter) from the cattle that graze within the pasture land. I walked the entire length of the discharge path through the pasture land and observed fresh waste material directly within the flow-path of the lagoon discharge. The effluent leaving the lagoon system will be negatively impacted by flowing through the pasture land. Therefore, limits more stringent than F-5 guidelines are not necessary. The following comments address the letter.
1. I agree with the effluent design objectives and compliance limits as presented for cBOD5, TSS and TP (20/25 mg/L, 20/25 mg/L and 0.75/1.0 mg/L), respectively. These values represent average concentrations based on a monthly sampling frequency of the final effluent.
2. Ammonia, E.coli and toxicity testing of the effluent are not required since the effluent flow path follows:
a. a municipal drainage ditch system and not a natural surface water body, and,
b. the effluent will become highly contaminated by animal waste generated nutrients (phosphorus/nitrogen), solids and E.coli within the pasture land flow-path prior to entering Strawberry Creek.

Please find attached a summary of work to date on the Little Current Wastewater
Treatment Lagoon upgrades. I have tried to incorporate the items discussed in our
November 2nd meeting, with a phase approach. The first phase for us is to establish
effluent criteria, so that we can select a process that will meet the criteria. The
summary includes our proposed effluent criteria, as well as a proposed sampling
regime, for consideration and comment by the Ministry. I have addressed this letter
to you as my primary point of contact, but I believe the review would be led by
Rod Sein (Surface Water Specialist), and I trust you will forward the

Little Current Wastewater Treatment Expansion
4.3.1 Introduction
The Town of NEMI conducted a Schedule C Class Environmental Assessment (EA) for the
Little Current Lagoon system in 2010 in order to review options to expand the capacity of the
wastewater treatment system. The existing system consists of a three-cell facultative lagoon with
seasonal discharges, in the spring and in the fall. The future capacity requirement was
determined to be 1100 m3/day. The preferred solution was identified as “Upgrade Existing
Lagoons with New Technology to Increase Capacity”. The Environmental Study Report (ESR)
recommends that the final decision be further evaluated at the time of detailed design. Two of the
options reviewed in detail were:
1. Intermittent Sand Filtration (ISF). This would involve a six month discharge period,
between April and October. This discharge was to outlet to the same drainage channel as
the existing lagoons. Additional lagoon capacity would be required to provide six months
of storage for the cold months when the ISF was not in operation. Continuous Alum
addition would take place at the final pumping station in order to provide chemical
precipitation of the phosphorus.
2. Submerged Aquatic Growth Reactor (SAGR). This would be a continuous discharge
system, to the existing drainage channel. Continuous Alum addition would take place at
the final pumping station in order to provide chemical precipitation of the phosphorus.
As part of the Class EA, a three-season receiving water assessment was undertaken to effluent
water channels downstream of the lagoons and support proposed new effluent limits. The
lagoons discharge to a municipal drain, which travels more than three kilometres through pasture
land before joining up with Strawberry Creek and ultimately Strawberry channel.
Effluent limits were proposed as detailed in Table 1 below.
Table 1 Recommended Design Objectives and Compliance Limits 2010 Class EA
Parameter Objective Limit
cBOD5 10 mg/l 15 mg/l
Total Suspended Solids 10 mg/l 15 mg/l
Total Phosphorus 0.75 mg/l 1.0 mg/l
Total NH3 Winter 5.0 mg/l 10.0 mg/l
Total NH3 Summer 1.5 mg/l 3.0 mg/l
E.Coli 200 cfu/100ml NA
Dissolved Oxygen 5.0 mg/l NA
The total estimated cost for each option (2010 dollars) was $3.5M. The Town has been trying to
secure funding to construct the upgrades since that time, but has not been successful to
date. During this time, and despite efforts to reduce Inflow and infiltrations, flows to the sanitary
system have continued to rise. There is insufficient capacity to store winter flows, and a result
early lagoon discharges have been occurring most springs.
Recent Work:
In order to address concerns with early spring discharges with the Little Current Wastewater
treatment lagoons, the Town, in consultation with the MOECC, considered potentially pursuing
the ISF / additional lagoon option as its preferred design. In order to allow time to fund the
project, the plan was to build additional retention capacity for winter storage in the near-term,
followed by the implementation of an ISF system in the future. No additional treatment capacity
would be granted by the MOECC until the future ISF system was constructed. The fourth lagoon
would simply provide additional retention capacity so that the existing rated capacity could be
properly treated.
The Town undertook a design for the forth lagoon cell. Flows over the past 7 years since the
original ESR was filed were reviewed. A geotechnical investigation, preliminary design, and cost
estimate was completed. Due to a number of factors (size, rock elevation, liner requirements), the
cost estimate for the lagoon portion only far exceeds the initial budget estimate for the entire
treatment system upgrades recommended in the Class EA.
The Town then reviewed the SAGR option to treat flow from the lagoons, which would be
reconfigured to discharge continuously to the receiving stream (via the SAGR). The capacity
would need to be increased from the 1100 m3/day outlined in the Class EA to approximately
1500 m3/day. This would require an addendum to the Class EA, assuming there were no
significant changes to the proposed solution.
At the request of the Town, the MOECC facilitated a meeting at their Sudbury office on
November 2nd, 2017. The purpose of the meeting was to review the status of the original Class
EA, receiving stream analysis, proposed effluent limits, and to update the MOECC on the recent
design work.
Meeting Review:
Those present at the meeting included:
Marnie Managhan (Water Supervisor MOECC)
Parise Drolet (Water Inspector MOECC)
Rod Sein (Surface Water Specialist MOECC)
Anneleis Eckert (Environmental Assessment Coordinator, MOECC)
Tony Guerrera (Greer Galloway Consulting Engineer)
Dave Williamson (CAO Town of NEMI)
Teleconference;
Deborah Sinclair (Hutchinson Environmental Consultants)
Frederick Lam (EAB wastewater engineer MOECC)
During the meeting the MOECC concurred that an additional assimilative capacity study for this
system would not be required, as there is no sensitive receiver downstream. The discharge is to a
municipal drain. Because the catchment area of the drain encompasses an agricultural area,
imposing strict effluent limits as proposed in the 2010 ESR document would be redundant and
would not positively impact the receiver.
It was determined that effluent quality from a standard operating lagoon should be acceptable in
this location. A limit of 25 mg/L BOD, 25 mg/L TSS, and 1.0 mg/L of Total Phosphorus was
discussed. Ammonia and toxicity testing would not be required. A SAGR system may not
necessarily be required. Some treatment will be required to address the concern of discharging
under ice cover.
As a result of the meeting, the consultant is to propose the following:
1) Proposed Effluent Limits;
2) Sampling Frequency;
3) The proposed flow capacity and justification showing a 20 to 25-year growth horizon;
4) A proposed method for revisions to the original Class EA, citing the Municipal Class EA
process;
5) Finalize the preferred design for the treatment process;
6) After any alterations to the Class EA have been completed, consultation requirements
have been met, and the Class EA has been finalized, the project would be able to move to
detailed design and tendering. The intent is to tender in 2018.
This report will address items one and two as listed above, and will be submitted to the Ministry
(Northern Technical Support) for review, comment, and concurrence. Item three will be
completed as a separate technical memorandum and included with the addendum to the Class
EA. Item four will be addressed under separate cover and submitted to the Ministry for there
information. Item five will be completed in the form of a treatment process report once effluent
criteria have been approved, and will be submitted to the Ministry (Norther Technical Support)
for review. The Class EA addendum can then be finalized.
Item 1: Effluent Limits and Effluent Objectives
The revised treatment capacity is to be approximately 1500 cubic metres per day (average day flow). The
recommended Little Current compliance limits and effluent objectives are shown in the Table 2 below.

Present; Marnie Managhan (Water Supervisor MOECC) Parise Drolet (Water Inspector MOECC) Rod Sein (Surface Water Specialist MOECC) Anneleis Eckert (Environmental Assessment Coordinator, MOECC) Tony Guerrera (Greer Galloway Consulting Engineer) Dave Williamson (CAO township of NEMI) Teleconference; Deborah Sinclair (Hutchinson Environmental Consultants) Frederick Lam (EAB wastewater engineer MOECC)
Rod (SW Specialist) has over 10 years of involvement with this file and is very familiar with the site and the adjacent properties.
The lagoon discharges to a municipal ditch that flows pass pasture land where livestock have access to the ditch and water prior to reaching Strawberry Creek.
An assimilative capacity study is not required because there is no sensitive receiver downstream‐the discharge is to a municipal drain.
The guidelines should be used to determine the effluent limits. BOD 25 mg/L, TSS 25mg/L and Phosphorus 1.0 mg/L.
Although there is no sensitive receiver and there’s an intermittent flow, the effluent should be non‐toxic, and would require additional treatment (aeration/ SAGR). I thought it was later determined that toxicity testing or ammonia limits would not apply, as the municipal drain is already impacted by the pasture land and treating for ammonia would not accomplish anything by the time the discharge reached Strawberry Creek. If there is no ammonia limit or toxicity concern, then a SAGR may not be required. ‐ Although there is no sensitive receiver and there’s an intermittent flow, the effluent should be non‐toxic, and would may require additional treatment (aeration and or SAGR).
‐ The proposal is a continuous discharge lagoon, therefore additional treatment is required undoubtedly in the winter months. Yes I believe this was to address the “discharge under ice” concern (hydrogen sulphide build up). Potentially aerating a portion of the lagoon train. We will need to establish the goal / target, if any. I did speak with my process fellow after the meeting, and he thought of something that I did not consider. With a lagoon, algae blooms can be a concern, particularly in the summer months. Algae can show up in the TSS results if we are doing a continuous discharge. I will consider this and may have some additional questions here regarding the MOECC’s position on algae affecting TSS on a lagoon discharge.
Deb Sinclair signed off from the teleconference. She was involved in the gather information and guidance to complete an assimilative capacity study or a dry ditch study. It was determined that neither of these studies are required.
The flow capacity is required to be increase to 15 000 m3/day. (Typo – 1500 m3/day) This is based on a projection flow of 25 years.
The Class EA may be required to be resubmitted or an addenda provision may apply. This depends on what was originally submitted in 2010 and what the final design and capacity will be.
Tony will be submitting another project design which will summarise the need to increase the flow capacity, additional treatment (SAGR/Aeration)effluent limits, sampling schedule, amendments to the Class EA (if any) within the next 3 months.
Parise will submit a Field Alert to update the existing ECA. The township is continuing to put forward efforts to try and reduce access flows to the
lagoon. Storm water discharges have been addressed, there are still some private residents that have their sumps/gutters connected to the sanitary system.
Although Frederick assisted in the meeting, he may not be the engineer assigned to the file, and documentation request is subject to change.

1.0 Introduction
1.1 Background
Greer Galloway was retained by the Town of Northeastern Manotulin and the Islands (NEMI) to complete the detailed design of a new lagoon cell for the Little Current Lagoon. The new lagoon cell was to be constructed as part of a phased implementation of the preferred option to increase capacity of the system as determined through a Class Environmental Assessment (Class EA) completed by Stantec (Stantec, 2010). During design of the new lagoon cell it became evident that influent sewage flows were higher than estimated during the Class EA and that constructing the cell was going to be technically challenging and cost excessive. In light of these challenges, further consultation with the Ministry of Environment and Climate Change (MOECC) led to the development of revised effluent criteria based on a continuous discharge operation (i.e. versus the current seasonal discharge operation). The MOECC has indicated that some form of enhanced treatment should be provided in consideration of the change of operation and Greer Galloway requested that J.L. Richards and Associates Limited (JLR) develop a design basis in support of the preparation of a Class EA amendment.
1.2 Lagoon Overview
The Little Current Sewage Lagoon (Current ECA No. 2249-89XRBU) consists of a three cell facultative lagoon treatment system. Wastewater is pumped from the main sewage pumping station, located at 5 Water Street, and directed to Cell no. 1 and from there it flows to Cell no. 2 and Cell no. 3. All cells currently operate on a fill and draw basis and discharge of the treated contents occurs twice per year in the spring and in the fall. Ferric sulphate is batch dosed directly into the lagoon cell for phosphorus removal prior to the discharge periods. No other type of treatment is currently provided. Treated effluent is discharged in the spring and fall into an approximately 7 km long ditch that passes though agricultural land and ultimately leads to Strawberry Channel of Lake Huron. Treated effluent can be discharged from Cells no. 2 or 3. The ECA does not provide a rated capacity for the site, however, design documents upon which the ECA was based on provide a rated capacity of 927 m3/day. A site plan is provided in Appendix ‘A’. A summary of the cell size and configuration from the Class EA (Stantec, 2010) is provided in Table 1. The total operating volume is estimated to be 166,854 m3. A study conducted in support of re-rating the lagoon reported the total operating volume as 168,524 m3 (Martin, 1990). For the purposes of this report the more conservative volume reported by Stantec has been used.

1.3 Design Influent Flow Rates
The proposed rated capacity of the lagoon is 1,500 m3/d based on flow projections provided by Geer Galloway. This is based on current measured flows and 20-year growth projection for the community of Little Current. The design basis is summarized in Table 2.

1.4 Design Influent Concentrations
Stantec (2010) used MOECC design guidelines for typical per capita loading to establish raw wastewater concentrations. The concentrations developed by Stantec were compared to the last three years of influent sampling results and appear to be generally a reasonable estimation of typical influent quality at the Little Current lagoon. For preliminary design purposes, however, the average influent concentrations for the past 3 years have been assumed. Where actual data is not available the concentrations from the Stantec (2010) ESR report have been assumed. The design influent characteristics are highlighted in Table 3.

1.5 Proposed Effluent Criteria
The proposed treated effluent quality requirements are summarized in Table 4 below. These criterion were developed in consultation with MOECC (letter dated January 12, 2018). It was determined that, due to the negative impact adjacent pasture lands have on effluent quality leaving the lagoon system, limits more stringent than F-5 guidelines are not necessary. Per direction from MOECC, ammonia, E. coli and toxicity testing of the effluent are not required since the effluent flow path follows: (1) a municipal drainage ditch system and not a natural surface water body, and (2) the effluent will become contaminated by animal waste generated nutrients (phosphorus/nitrogen), solids and E. coli within the pasture land flow-path prior to entering Strawberry Creek.

2.0 Design Concept
2.1 Overview
The proposed treatment for the Little Current Lagoon consists of four components:
- Facultative lagoons for cBOD and TSS removal (existing); - Continuous ferric sulfate addition for phosphorus removal (new); - Post-aeration polishing cell for hydrogen sulphide (H2S) removal (new); - Baffle curtains, valve and piping modifications to support process modifications (new).
2.2 Facultative Lagoons
The MOECC Design Guidelines recommend that the average BOD5 loading to a facultative lagoon be 22 kg/(ha*d) or less. The BOD5 loading under various cell loading scenarios is summarized in Table 5 below:
Table 5 BOD5 Loading and Detention Time for Various Cell Configurations
Design Flow Cells Loaded Total Area (ha) BOD5 Loading (kg/(ha*d))
Detention Time (days)
Annual Average Flow (AAF) 1500 m3/day
1 & 2 8.54 30 86 1 & 3 6.48 40 66 2 & 3 6.92 37 70
1, 2, & 3 10.97 24 110 All three lagoon cells are required to achieve the BOD5 loading rate recommended by the MOECC. If only two cells are in service during maintenance activities, the BOD5 loading exceeds the MOECC guideline. It is, however, generally accepted that under these circumstances, the maximum BOD5 loading rate can be exceeded. BOD5 removal performance increases during warm weather months and any required maintenance can be done during these months. Based on a capacity assessment conducted by the MOECC (1990) the design hydraulic detention time for the continuous discharge lagoon was 180 days. The MOECC guideline does not provide a minimum detention time for continuous discharge lagoons, however, the duration of the cold weather period (i.e. lagoon contents < 5 deg. C) provides a reasonable guide. This would typically be between December 1 to March 15 (103 days), and a detention time of 110 days is sufficient.

2.3 Ferric Sulfate Feed System
As part of the newly proposed continuous discharge operation, a ferric sulfate (Fe2(SO4)3) feed system is proposed with dosage between Cell No. 2 and Cell. No 3. As noted previously, the proposed lagoon flow rate is to be 1500 m3/day, and the anticipated phosphate concentration in the influent is 5.6 mg/L as P. This concentration is considered conservative, as natural phosphorus removal will occur in cell No. 1 and cell No. 2 particularly during the warmer summer-fall treatment periods. The ferric sulfate solution currently used by the plant operator is 60% Fe2(SO4)3 (12% Fe3+) with a specific gravity of approximately 1.5 kg/L. The specific dosage required for the modified plant will need to be adjusted based on actual phosphorus concentration and jar testing may be required to determine the optimum dosing. On average, however, 100 L of ferric sulfate solution is expected to be required per day to achieve the effluent objective of 0.75 mg/L (refer to Appendix ‘B’ for calculations). Operators currently apply a 20% factor of safety to the dosage, which results in a dosage of 120 L per day. The ferric feed system will generally consist of a bulk storage tank, metering pumps, and discharge piping. Operations staff have indicated that the bulk delivery of solution is 9000 L, which equates to approximately 2.5 months of storage (75 days). Due to the size of the tank, the bulk storage tank is proposed to be installed outside of the blower building and design will need to incorporate provisions for full spill containment. To avoid freezing in the winter months, heat tracing and insulation will be required for the tank and chemical feed lines.
2.4 Post-Aeration Polishing Cell
With cold winter temperatures causing ice to form on the surface of the lagoon cells, the formation of hydrogen sulphide (H2S) under the ice cover will occur through the water column. As a result, continuous (winter) discharge of effluent could result in toxicity and odour problems. To mitigate this issue, a post-aeration cell with the objective to remove hydrogen sulphide (H2S) is proposed. Based on MOECC design guidelines, the cell should have a depth of 3 to 4 m; have a L/W ratio of 4:1 and provide at least 24 hours retention time. The required cell size is relatively small to achieve a 4:1 L/W ratio, however, the retention time could be achieved with a cell 4m deep (water operating depth 3.5) that is 50 m x 50 m at the top of the berm. A shallower cell could also be used and the size adjusted to maintain the 24 hour retention time. The exact shape and depth of the cell can be further refined during detailed design. Oxygen should be supplied to satisfy both the oxygen demand for BOD5 (or 1.2 kg O2/kg cBOD5) and H2S oxidation (1.0 kg O2/kg H2S). Table 6 summarize the oxygen requirements for BOD5 and H2S removal.
Table 6 Oxygen Requirements for H2S Removal
Parameter Concentration Loading O2 Required Effluent BOD5 20 mg/L 30 kg/day 36 Effluent H2S 20 mg/L 30 kg/day 30 Total 66 kg O2/ day
Influent diffusion should be provided to equalize the loading across the influent end of the post-aeration cell and a static tube air system should be provided. The blowers will be housed in a new chemical pumping/blower building, and will operate on an as needed basis.

2.5 Baffle Curtains, Piping and Valve Modifications and Cell Configuration
The current flow pattern through the lagoon system will be modified. The current flow pattern allows the sewage to enter Cell 1 or Cell 2. Under the normal operating mode, the flow enters Cell 1 and is then split in two to Cell 2 and Cell 3. To move from seasonal discharge to continuous discharge, it will be important to implement a configuration that promotes series flow through the lagoon system while minimizing short-circuiting. To achieve these objectives, we are proposing a new configuration as well as the installation of curtains in the lagoons. New interconnecting pipes with valves will also need to be installed to provide operational flexibility and allow the possibility to put any lagoon out of service for maintenance. Figure 1 illustrates the proposed cell configuration, the position of the curtains and piping and valve modifications. With the modifications, the following flow patterns will be possible:
• Normal flow pattern: Cell 1 to Cell 2 to Cell 3 • Alternate flow pattern No. 1: Cell 1 to Cell 2 (Cell 3 out of service) • Alternate flow pattern No. 2: Cell 1 to Cell 3 (Cell 2 out of service) • Alternate flow pattern No. 3: Cell 3 only (Cell 1 and 2 out of service)
The post-aeration cell will be constructed downstream of the lagoon system. A new 300 mm diameter pipe installed along the southern edge of Cell 3 will allow the flow to go from Lagoon 2 to the post-aeration lagoon, while by-passing Cell 3. Ferric sulfate will be dosed in the effluent pipe connecting Cell 1 and Cell 2. Additional consideration may need to given to chemical diffusion and mixing at the injection point during detailed design.
3.0 Cost Estimate
An Opinion of Probable Construction Costs (OPCC) with a Class ‘D’ (Concept Design) level of accuracy was developed for each of the new requirements. The OPCC was developed based on a combination of unit cost analysis format (i.e. cost per m2) and element cost analysis format (i.e. cost per item). In certain instances, allowances have been made to account for design elements that have yet to be fully developed; these allowances are based on past experience on similar projects and professional judgment. The Class D (Concept Design) OPCC developed for the proposed construction is $876,000 (excluding HST). The full cost breakdown is provided in Appendix ‘C’.

a. Dosage = 2.0 mole Fe (Fedose) per 1.0 mole P (Pini) to remove 98% 1
b. Iron Required = 2* (Fedose/Pini) = 2 * (55.85/30.97) = 3.61 kg Fe/ kg P
3. Determine the amount of ferric sulfate solution required per kg P to be removed. a. Ferric sulfate dose = (3.61 kg Fe/ 1 kg P) * (L ferric solution/0.126 kg Fe)
= 28.65 L ferric solution/kg P
4. Determine the amount of ferric sulfate solution required per day. a. Ferric sulfate solution per day
= (1,500,000 L/d)*(3.1 mg/L–0.75 mg/L)/(1x106 mg/kg)*28.65 L solution/d = 100 L ferric sulfate solution/day

Town of Northeastern Manitoulin and the Islands NOTICE OF FILING OF ADDENDUM
Little Current Sewage Treatment System Upgrades Class Environmental Assessment
The Town of Northeastern Manitoulin and the Islands (Town) is proposing to undertake upgrades to the Little Current sewage system. These upgrades will improve the quality of treated effluent, improve the quality of receiving water environments and increase the capacity of the treatment system to support long-term growth and development in the community of Little Current. The project was planned in accordance with the requirements for a Schedule “C” Municipal Class Environmental Assessment. The Environmental Study Report (ESR) issued January 2011 recommended upgrading the existing lagoons with new technology to increase treatment capacity. Final selection of the preferred design concept was deferred to the preliminary design phase. An Addendum to the ESR is now available containing details of the preferred treatment process based on updated design flows and effluent criteria. Please note that only the changes proposed in the Addendum are open for review. The Addendum is available for review on the Town website. For more information or to provide written comments please email the following project contact by August 9, 2018: Tony Guerrera, P.Eng. (email: [email protected]) The Greer Galloway Group Inc. 1620 Wallbridge-Loyalist Road Belleville, ON K8N 4Z5 Telephone: (613) 966-3068 Fax: (613) 966-3087 If concerns regarding the project changes covered by this Addendum arise that cannot be resolved in discussion with the Town, a person/party may request that the Minister of the Environment and Climate Change make an order for the project to comply with Part II of the Environmental Assessment Act (referred to as a “Part II Order”), which would elevate the level of assessment and require the Town to undertake additional consultation. Requests for a Part II Order must be received by the Minister (address below) by August 9, 2018.
