1. INTRODUCTION

The Logan Water Infrastructure Alliance (LoganWIA) on behalf of Logan City Council (Council) has developed

this site Based Management Plan (SBMP) for the Cedar Grove Waste Water Treatment Plant (WWTP), located

at Cedar Grove Road, Dennis Road and Rogers Road in Cedar Grove QLD (the site).

Stage 1 of the WWTP has a total design capacity of 20,000 equivalent persons (EP). This is defined as an

Environmentally Relevant Activity (ERA) 63(1)(e) as defined under Schedule 2 of the Environmental Protection

Regulation 2008, and may only be conducted under the terms and conditions of the of the Environmental

Authority (EA) (approval in progress). This SBMP has been developed and will be implemented to ensure

compliance with the likely EA conditions for the site.

1.1 Scope

This Site Based Management Plan (SBMP) provides a structured framework to:

address site environmental objectives and standards

identify potential environmental harm that may occur from operation of the site

establish documented management measures

identify extraordinary factors that may cause environmental harm, and establish

response / contingency plans

ensure that all persons working on the site are aware of the environmental risks and trained in

application of management measures and contingency plans

implement monitoring of environmental performance to ensure effectiveness of measures and

contingency plans, as required

ensure accurate and reliable record keeping to assist with internal and external communication of

environmental performance

ensure periodic review of environmental performance to guide continual improvement.

This SBMP is a preliminary document and will be updated to reflect the conditions of the EA for the WWTP,

when approved.

1.2 Associated documents

Associated plans/programs for the Cedar Grove WWTP are as follows:

Netserv Treatment Operations Management Plan (incorporating the Water Quality Release

Improvement Plan)

NetServ Recycled Water Management Plan (incorporating the Contaminant and Release

Reduction Strategy)

Water NetServ Sewer Overflow Management Plan (Logan City Council 2014)

Wastewater Overflow Abatement Strategy ( LWA 2014)


Sewerage Overflow Management Strategy (LWA 2010)

Further plans that will be developed for the Cedar Grove WWTP, or will be adapted from existing

Council plans to include Cedar Grove WWTP are expected to include:

- Waste Management Plan

- Emergency Response Plan

- Wetland Management Plan.

1.3 Site description

The site is located along Cedar Grove Road, Dennis Road and Rogers Road in Cedar Grove. The Cedar

Grove WWTP site has a total area of approximately 203.9 hectares (ha) which is made up of six land parcels

owned by Council as outlined in Table 1-1.

A pipeline leading from the Cedar Grove WWTP to the Logan River will traverse Lot 200 on RP200030, a

freehold property owned by Queensland Bulk Water Supply Authority (trading as Seqwater) (refer to Table 1-

1).

DNRM

A Council road reserve (Rogers Road) also exists through the site, leading to a lot which is held in trust by

Seqwater. Cedar Grove Road forms the southern boundary to the site, while the Logan River forms the

northern and part of the western boundary. Cedar Grove village lies southeast of the site, and agricultural land

lies beyond the boundaries in all other directions. The site is largely cleared of woody vegetation and is

currently used for grazing of cattle.


1.4 Process description

The proposed WWTP will be a Membrane Bioreactor (MBR) process. The following elements are proposed:

An inlet works, including fine screening and grit removal

A bypass system which will divert flows above 5 x ADWF around the WWTP, after screening

A two basin bioreactor with an integrated four membrane train MBR system capable of processing

instantaneous flows up to 5 x ADWF

A chemical storage and dosing facility for alum, sodium hypochlorite, caustic and citric acid

Bioreactor and membrane aeration blowers inside a blower building

An aerated sludge storage tank for pre-thickened waste activated sludge from the bioreactors

A biosolids dewatering facility comprising a high performance decanter centrifuge or screw press and

polymer batching and dosing system in a sludge dewatering building.

A dewatered biosolids temporary storage and load-out facility

A control building

An odour control system to remove and treat odour from the inlet works structure and at influent flow

splitter at the head of the bioreactors

A generator unit to supply backup power to the plant

A compressed air system to supply the pneumatic actuated valves and any other pneumatic items.

A constructed surface flow wetland is proposed to be installed at the site to provide additional treatment and

in particular, nutrient removal from the effluent. The wetlands will total 10.2 ha in area, constructed over three

stages, each stage comprising 2 cells of 1.7 ha each as shown in Attachment 1. Based on existing growth

projections, cells would be constructed in 2019, 2022 and 2025. Cells will be planted with a range of suitable

wetland species.

All flows treated through the MBR will be discharged to a constructed wetland system. This system will also

be design to accommodate peak wet weather flows of up to 6.5 x ADWF, which is above the adopted peak

wet weather flows (PWWF) of 1000L/EP which has been adopted for new developments in Council’s Desired

Standards of Service (DSS).

A schematic diagram of the WWTP process is presented in Figure 1-1.

2. ENVIRONMENTAL MANAGEMENT

This SBMP forms part of the overarching Wastewater Services Integrated Environmental Management System

(IEMS) for Council. The IEMS documents Council’s approach for managing potential environmental impacts

of Council’s products, services and activities across the water business. All site operations and management

measures are to be carried out in a manner consistent with the IEMS.

Council’s IEMS incorporates the following:

Environmental Policy

Environmental Aspects and Impacts

Objectives, Targets and Programs

Resources, Roles, Responsibility and Authority

Competence, Training and Awareness

Communication

Documentation

Control of documents

Operational control

Emergency preparedness and response

Monitoring and Measurement

Evaluation and compliance

Nonconformity, corrective action and preventative action

Control of records

Internal and external audits

Management review including continuous Improvement of the EMS.

The SBMP is the guiding document for the site–specific environmental management controls and procedures

adopted as part of the operation of the Cedar Grove WWTP. The SBMP contains references to other

documents including procedures, plans, manuals and registers that are maintained as a part of the IEMS.

2.1 Environmental authority

The operation of the Cedar Grove WWTP and attached wastewater network is classified as the following

Environmentally Relevant Activity (ERA) under the Environmental Protection Act 1994:

ERA 63 (1e) – Sewage Treatment: operating sewage treatment works other than no-release works, with a

total daily peak design capacity of more than 10,000 but not more than 50,000Equivalent Persons.

Under the provisions of the Environmental Protection Act 1994, an Environmental Authority (EA) for carrying

out the ERA is required. The EA will include series of conditions that must be complied with to ensure that

potential impacts on the environment are minimised during the life of the ERA. This SBMP will be updated

once the EA has been issued, to reflect the requirements of the conditions.


2.2 Effluent volumes

Daily design flows will be based on Councils DSS. Average annual flows are calculated based on inflow data

collected from Flagstone WWTP, which are approximately 1.1 x ADWF. Table 2-1 summarises the design

capacity of the Cedar Grove WWTP.

2.4 Environmental incidents

Whilst all best efforts are made by operators to prevent pollution, at times environmental incidents can still

occur which may cause environmental harm or nuisance. In such instances, Council must respond in

accordance with the EP Act Duty to Notify of Environmental Harm, which states that:

While carrying out an activity if a person becomes aware of an event that causes serious or material

environmental harm the person has a duty to notify the employer / administering authority.

As such, in the event of an environmental incident in which environmental harm or nuisance is suspected; for

example, a dry weather bypass, major WWTP process upset or a sewage overflow that has the potential to

impact on the environment, the following notification procedure is to be followed.

During work hours

1. The operator must notify their Supervisor as soon as practically possible via telephone, but no later

than 24 hours after initially becoming aware of an incident where environmental harm may be caused

or threatened.

2. The Supervisor must in turn notify the Environmental Management Systems Team via telephone (3412

4335) and the Treatment Program Leader and provide the following details:

the incident details and location specifics;

the contact details of the relevant supervisor on-site; and

a short summary of the situation.

3. The Environmental Management Systems team will investigate the incident in conjunction with the on-

site supervisor, record relevant information and carry out the necessary stakeholder notifications and

regulatory reporting on behalf of Council where required.

4. The Treatment Program Leader will oversee corrective actions and notify Workplace Health & Safety

if required.


After work hours

1. The operator must notify their supervisor on-call as soon as practically possible via telephone, but no

later than 24 hours after initially becoming aware of an incident where environmental harm may be

threatened.

2. The on-call supervisor must in turn notify the Environmental Management Systems Team via

telephone and provide the details of the incident (as per work hours procedure). Environmental

Management Systems Team After Hours Number: 3412 4335. (The phone will be diverted to the on-

call Environmental Management Systems Team Member). The Treatment Program Leader is also to

be notified.
