Syrah has applied to the Louisiana Department of Environmental Quality for air and water permits
obviously LDEQ can alter the terms of what Syrah is currently proposing. It simply an application. And LDEQ actually has some of the most strict regulations as far as state agencies go. I'll wait and see what happens with the permit and then pass judgement.

The water released will have salt concentration 3x that of ocean water.

There's no way any regulatory agency would allow that.

0% chance that any new permit is ever written that allows them to discharge 10% salt into a body of water that is for arguments sake fresh

I could possibly see them maybe doing it in some sort of TWA scenario, but that's still unlikely.

I don't monitor or watch pollution numbers. Everyone says the worst pollution in the river is from the fertilizer run off from farm lands. Much of this water also goes into the Atchafalaya river and then Atchafalaya swamp. No one mentions high levels of pollution in this area.

I’m sticking with 0%

The process might produce a solution that in 10% salt as a byproduct, but there is no way that is getting permitted to be pumped into an estuary. You know how much money these plants spend getting the water they pump out cleaner than they pump in?

The part that makes the fertilizer issue a big deal is the algae bloom that causes oxygen deficiency.

As I understand it, it doesn't affect the Atchafalaya the same way as it essentially acts as a giant filter.

That was another question I had. What is their water source?

Someone probably found the proposed salinity concentration for an internal outfall that flows to a treatment process or offsite to a POTW and assumed that’s going to the estuary.

I’m curious now so I’m going to see if anything is on EDMS for this site later tonight

I’ve heard the same thing, but it’s more than just farmers, the general public does its fair share of spilling gas, oil, pesticides, paints, etc

The problem in Louisiana is that we are managing 47% of the agricultural runoff of the lower 48 in the Mississippi River.

re: Proposed Graphite Plant for Port Manchac
This is not a battery plant. This is a graphite processing plant(which is 100% carbon). Even though the graphite will be used in battery production, it's totally different. Battery plants that caused the problems of pollution in the past were lead acid battery plants. Discharges of effluent from any industry have restrictive ranges set up in their permits that they have to adhere to. Parameters like salinity and pH cannot be drastically out of range from the receiving stream waters. The people quoted in the OP link are all known environmental activists trying to scare the hell out everyone.

Among many problems.

My comments about the general population contributing its fair share, look at Bayou Manchac which drains most of Baton Rouge to the Amite. An ideas what that water quality looks like?

Mining purer graphite makes it even more environmentally friendly.


It also uses less resources to make the graphite needed..

Especially since salinity is measured in parts per thousand. Percent is parts per hundred. Sea water is 32-35 ppt which is 3.2 -3.5 %. That means what is reported is 3X the salinity of pure sea water. 0% Chance that gets approved

re: Proposed Graphite Plant for Port Manchac
Permit Application on EDMS specifies that the effluent will be passed through reverse osmosis to lower salinity, and then pH will be neutralized prior to discharge.

re: Proposed Graphite Plant for Port Manchac
If they are running their waste process water that contains salt through a RO process their will be very little precipitants in it.

I drove by Port Manchac today.

It is inconceivable to me that people are whining about this almost inert little plant given the crap that is stored and processed there today. I bet you there were over 100 IBCs outside of buildings there today.

I don't have a dog in this fight with this plant happening, just expressing my opinion that there is no chance that with today's EPA and DEQ standards will a new construction plant get a permit that allows them to discharge effluent that is "3x the salt concentration of the ocean" into Pass Manchac or North Pass, especially considering the state of the coast.
