AGL could you please tell me which chemicals you will be using in your odorisation processes?

Can you guarantee there will be no spills or leaks either onsite or during delivery?

How will these chemicals for the odorisation process be delivered to site? 

 If a spill or a leak ( god forbid!) were to occur ,what crisis measures have you put in place?

What effect does exposure to these chemicals have on human health?

What effect does a spill/leak of odorant chemicals have upon soil and water?

I am also very concerned about the use of chemicals in the environment, they could leach into the food chain quite easily. This cannot be prevented at all if chemicals are used.

Hi @KerryRainer,  

 

Sorry for the delay in responding to you, we had to confer with our colleagues at APA for further information.

 

We understand your concern about the use of chemicals. APA takes the spillage of liquid odorant very seriously as it has the ability to affect public safety.

 

APA has dozens of odorant injection facilities across the country and have a standing contract with a supplier for odorant delivery. That contractor is the same contractor that is designing and supplying the odorant equipment for the Crib Point Pakenham pipeline. 

  

To answer your specific questions, APA use a chemical called Spotleak 1005.

  

The odorant is supplied on an isotainer, specially designed for the transport of flammable liquids, delivered on a truck. The truck will park in a specifically designed truck bund that can hold all of volume of liquid supplied in an isotainer if a leak should occur. 

  

The transfer of liquid from the isotainer to the storage vessels is via a pump and specialised hoses. The pump and hoses remain the property of APA to control the integrity of hose connections and performance of the pump. The transfer process uses a closed loop system where the liquid is pumped into the storage and the vapour is returned back to the isotainer to remove the need to vent or flare the vapour. 

  

The odorant liquid is stored in vessels that are positioned in a separate bund to the truck bund and can hold all the liquid from a spill. 

  

Rain water collected in the bunds is not released before it is checked by a technician and is a manual process. So any leaks that occur are not released into the environment. 

  

Odorant spills are rare but we must prepare for any worst case scenario. It will be cleaned up with spill kits that are located at Crib Point. The materials used during the clean up will be disposed of at an appropriate disposal location. 

  

The odorant transfer pump, odorant injection pump and all odorant handling materials are contained in a separate building at Crib Point. This building is constantly purged with air to ensure no smell escapes the building. All of the expelled air from the building is pushed through a series of drums of activated carbon that extract the smell.   

  

APA also carry Mercaptan Odorant Neutraliser (MON) to clean-up the smell at Crib Point, in case of small leak. 

 

There are a number of regulators who will be involved to ensure we meet the highest safety standards.  These regulators include: 

  • the pipeline regulation unit at Department of Environment, Land, Water and Planning (DELWP)
  • Energy Safe Victoria
  • the Australian Maritime Safety Authority (AMSA)
  • Port of Hastings Development Authority
  • Worksafe Victoria
  • Victorian Regional Channels Authority (VRCA) and the Harbour Master
  • Transport Safety Victoria (TSV) and Maritime Safety Victoria and
  • the Office of Transport Security (Cth).

Thank you for answering some of my questions LachlanS. Appreciated.

Would you be so kind as to answer the three questions you seem to have missed?

What effect does exposure to these chemicals have on human health?

What effect does a spill/leak of odorant chemicals have upon soil and water?

Can you guarantee there will be no spills or leaks either onsite or during delivery?

Hi KerryRainer,

 

We’d like to apologise for not answering those particular specifics of your question relating to the odorisation chemical.

 

As APA are managing the odorisation side of the project, we will need to speak with their experts about Spotleak 1005.

 

As I am sure you can imagine, this may take some time.

 

I am just letting you know that we have received your question and are working on a response as quickly as possible.

 

Thanks,

Lachlan

Hi KerryRainer,

 

We appreciate your concerns about potential spillage.

 

The Safety Data Sheet for Spotleak 1005 lists the effects on humans if they are exposed.

 

There would be an average of one odorant truck every two months delivering Mercaptan to the facility. An APA Technician will open the site and supervise the delivery with the work to be undertaken by specialised transport staff. They would be required to wear the appropriate Personal Protective Equipment (PPE).

 

The product is handled over a sealed area at all times. The Mercaptan is transported over sealed roads. During transfer (between the truck and the tank) it is handled over a bunded concrete area that is easy to clean.

 

Although we can’t guarantee a spill/leak would never occur, APA employs the highest standard safety procedures at our odorant injection facilities operating across the country and spills/leaks are rare.

 

Thanks,

@Madeline_APA

 

Thank you for your reply although you seem to have overlooked one important question I posed which was " What effect does a spill/leak of odorant chemicals have upon soil and water?"

 

I followed your link and read the safety data sheet 

Odorant injection package – Crib point to Pakenham pipeline project Controlled Document

Product Name: Spotleak 1005 Reference No: ICE000102 Issued: 2016-06-06 Version: 1.3

 Aside from the recent revision of Change in Accidental Release measures, is this the latest safety data sheet prepared for your proposal by Chemical Data Services Pty Ltd as the research it is based on is from or before 2016?

" 16. OTHER INFORMATION Reasons for issue: Revised Change in Accidental Release Measures This Safety Data Sheet has been prepared by Chemical Data Services Pty Ltd on behalf of its client. Safety Data Sheets are updated frequently. Please ensure that you have a current copy. This information was prepared in good faith from the best information available at the time of issue. It is based on the present level of research and to this extent we believe it is accurate.

Point 12 of the Safety Data sheet exacerbates my concerns and the need for my unanswered question to be answered.

"

  1. ECOLOGICAL INFORMATION Avoid contaminating waterways. Acute aquatic hazard: This material has been classified as a Category Acute 3 Hazard. Acute toxicity estimate (based on ingredients): 10 - 100 mg/L Long-term aquatic hazard: This material has been classified as a Category Chronic 2 Hazard. Non-rapidly or rapidly degradable substance for which there are adequate chronic toxicity data available OR in the absence of chronic toxicity data, Acute toxicity estimate (based on ingredients): 1 - 10 mg/L, where the substance is not rapidly degradable and/or BCF ≥ 500 and/or log Kow ≥ 4. Ecotoxicity: No information available. Persistence and degradability: No information available. Bioaccumulative potential: No information available. Mobility: No information available."

 

This material is classified as a Marine Pollutant (P) according to the International Maritime Dangerous Goods Code.
