Gunnar (without James this time) gives it a go to get to the bottom of the very basics of what we need to think of around stormwater on a site. There are few better suited to talk about the subject than our guest Mircea Stancu, the founder of Cleanstormwater.

Mircea is a civil engineer, software engineer and, you guessed it, an expert in anything related to stormwater. He is also quite a flamboyant guest and he and Gunnar managed to put together a show case of the very best of (what Gunnar at least calls) attractive European accents.

The two of them briefly talk about a dispute between Mircea and Melbourne Water, played out publicly on LinkedIn. If you feel like a little bit of entertainment, grab your popcorn and have a look at these videos:

James K (James Karagiannis) has personally completed a stack of waste classifications. And in addition, he has reviewed somewhere between 1,000 and 1,200 reports written by other consultants for our clients. That gives him a rare, panoramic view of what great looks like … and what misses the mark.

Gunnar and Hammond, James Hammond, sit down with him to unpack what he sees when reviewing these reports: some work that’s brilliant, some … not so much. We talk about the “not so much” parts in this episode.

The original plan was to listen to James K. But with Gunnar’s well-known habit of let’s say, sharing his thoughts, and Hammond’s nerdy knowledge in resource recovery and compliance, there may have been a little more talking than listening at times.

Still, we think you’ll enjoy the conversation, have a few laugh and maybe even pick up a few tips to sharpen your own waste classification skills. Enjoy!

Tony Chappel, the CEO of the NSW EPA, is our guest today, so we are definitely back with a bang after the summer holidays.

Gunnar and James are (surprisingly!) well-prepared and keep the conversation on track as they dive into Tony’s journey to leading the EPA, his early priorities, the role of politics in environmental regulation, and the importance of deep listening in leadership. They explore everything from the OCSE paper and the EPA's potential collaboration with industry bodies, to the tricky disconnect between waste and contaminated sites, the zero-tolerance stance on asbestos in waste, updates to the ASC NEPM, and the growing pressures on landfill capacity.

And yes, Gunnar did try for a get-out-of-jail-free card from Tony… but no luck this time (nice try, though)!

Three experts, one great conversation, and a rare look into the leadership and direction of the NSW EPA. This is definitely one episode you won’t want to miss.

Electric Vehicles are basically half price in Australia right now, thanks to some little-known government incentives. Gunnar and James decided it was the perfect time to talk… tax. Yes, tax. And you thought resource recovery was a boring subject, right?

But before you judge, listen to this episodes. Gunnar and James have brought in the big guns: chartered accountant Paul Mills (paulybmills at gmail.com).

It really sounds like the beginning of a bad joke: Two engineers and an accountant meet for a podcast ...

Somehow yet again they pull it off, though. This episode is full of genuinely valuable info. Paul explains what Fringe Benefits Tax (FBT) actually is, who pays it, and whether your lease company or car dealers are lying to you with their 'tax advice' (spoiler: probably). They also unpack the confusing mess that is the difference between a car loan, a lease, and a novated lease.

And most importantly: The kicker is that EVs (full EVs, not wannabe EV hybrids) are FBT exempt in Australia. If you do it right, that knocks off around 50% off the prices of buying an EV. How? You gotta listen to find out.

But remember: While Paul is brilliant, this podcast is still mainly about contaminated sites and resource recovery (some call it dirt and rubbish). So don’t go making financial decisions based on what you heard here without getting your own advice.

Gunnar claims almost all duplicates we take serve close to no purpose. If you want to know why, have a listen and be entertained and informed at the same time.

The OGs are back together in this episode, and quite an unusual one it is. This times it is James who goes on a few rants, quite to Gunnar's amusement. Of course, Gunnar has a few things to say as well and he will definitively ruffle some feathers with this episode.

We start off with playing Wikileaks by talking about a letter the EPA sent to all auditors regarding the staged introduction of V3 of the PFAS National Environmental Management Plan (NEMP) and also a clarification regarding PFAS and the Duty to Report. (Plug to our previous Episode #25 The Duty to Report).

Then Gunnar and James hash out some ideas on duplicates, high RPDs, re-running of samples, basic statistics, experimental setups in science and why being 'conservative' might not be delivering the results you think it is.

Episodes we talk about:

#29 The New AS5370 Standard with Linda Apthorpe

#25 The Duty to Report with Elizabeth Wild.

#11 The Sampling Evolution with Ross McFarland

Attention Asbestos in Soils Specialists, there is a new kid in town. The Australian Standard 4964-2004 Method for the qualitative identification of asbestos in bulk samples has been superseded with a new AS 5370.

What's different? What's better, what's worse? Why are we reporting below the detection and below the reporting limit? Is NATA on board with it? What do all those different sub-categories the laboratories report actually mean?

Gunnar is talking to Linda Apthorpe, a Certified Occupational Hygienist and Fellow of the Australian Institute of Occupational Hygienists (AIOH). Linda is Associate Principal Occupational Hygienist at Hibbs in Sydney, a Lecturer at the University of Wollongong, author of multiple scientific papers and speaker at a variety of professional development seminars. There are very few who are better suited to talk about this subject, especially since Linda was also on the panel of people who developed the new Standard.

James was unfortunately not there to keep Gunnar in check, and you guessed it, that resulted in not one, not two, but at least three (in)famous Gu-Rants in this episode. Some would say that alone makes this episode compulsory listening for anybody in the industry.

The Office of Chief Scientist and Engineer (OCSE) has issued recommendations concerning asbestos in waste and soil. Sarah Mansfield, Special Counsel (and environmental law superstar) at Norton Rose Fulbright, breaks down the key points and their legal implications.

Given the focus on the PoEO Act and its handling of asbestos, you'd expect at least one of our hosts to go off the rails with a classic, epic rant. But, against all odds, age, wisdom, and a dash of professionalism took the reins—so much so that this episode doesn’t even come close to earning the 'explicit' rating it sometimes gets on various platforms.

Gunnar's composure alone is a highlight (though he admits to biting his tongue to the point of unhealthiness!). Add to that the invaluable insights from James and Sarah, and you've got an episode well worth your time. We loved making it as always, and we hope you enjoy every moment.

Rod Harwood - do we need to say anything else?

There are few who have had more influence on our industry and who have contributed more than Rod. Gunnar had a chat with Rod and while they reminisce about 'the good old days', Rod sprinkles in some anecdotes of his impressive career and shares gems of his incredible knowledge as an engineer and a business man.

James was unfortunately unavailable (you know, work and stuff ...), but we promise, this is one everybody in our industry will enjoy.
