an area

ol

the

tor

a

100 kW

Genivar

is

to

revise the contract

drawings

to

reflect

the

selected

location for

the

biogas

cooling

bed

between

the

dgester

and

the control

and dewatering

building/hydrollzer.

Genivar

is

to look

into

providing

a

double door

for

lhe

drum scren

room

for removal

of the

drum

scren, if

required.

24 hour leakage

testing

will

be

provided

for

each

of the

concrete tanks

on

site,

including

the

dgester,

hydrolizer

tank, digestate

storag

tank

and FOG

tank.

Water utilized

to

perform

th

tosting in

one tank

should

be

utilized

in

the

other tanks.

The

digester

and

hydrolizer

will

be

provided

with

an uttrasonic

transducer

for level

measurement

and

for alarming

requirements.

A

float

switch will

be

provided

in

the

digestate

storage tank

to

provide

a

high alarm

signal.

Ventilation

ducting for

the

pasteurizer

unit

is

to be

provided

to tha odour

control unit.

Odours

only

occur when

the FOG

tank is

belng

filled.

Maple

Reinders is

to contact

Baycor

(drum

screen

supplier) concerning

the

odour control

reguirements

for

the drum

screen.

There

was

som

concsm

that

the digestate

storage

tank will

produce

odours.

CH4

statd

lhat

odourE

are not normally

producd,

but

sometimes they can

happen.

CH4

stated that

the

destate

storage

tank

could

be covered

as needed.

CH4s design

submittal

shall

show

a

list

of

Control

requiremants

scren may

require

additional

storage and

also a booster

pump

to

the

worse

case

scenario

flow

requirement.

Maple Beinders is

to dscuss

with

Baycor

concemng

Maple Reinders

is

to

discuss with

Baycor

conceming

the best

design for

lhe

transfer

pumps

to

provide

dewatered

septage

to the

digester

and

hydrolizer.

An inline

system

could

possibly

be

provided

with

progressive

cavity

pumps,

thereby

eliminating

a

sump. Thls

shoutd

also

remove

any issues with

odour after

lhe

drum

screen.

It

was

proposed

by Maple

Reinders

to install

a

flushing

connecton

to

tha hydrolizer,

provided

via

use of a

Y'connection

and isolation

valves.

Normal

flow

to the

hydrolizer

will be by

gravity.

lt

is

tikety

that

the

transfer

pipe

from

the separator

to th

hydrolizer

will

be

just

below

grade.

Therefore,

lhe

pipe

will ba

required

to

be insulated.

Genivar

is

to

discuss

furthar with

Maple

Reinders

regarding

the flushing

connection.

A

recrculation

lne from

the digester

to

to be

shown on
