shaky strokes
The Invisible Flame, in today’s post.

Pictured above is the so called “Unnamed Canal” tributary of Newtown Creek, found in Brooklyn’s Greenpoint. Roughly analogous to North Henry Street’s intersection with Kingsland Avenue, were North Henry’s northern terminus not enclosed entirely within the NYC DEP’s Newtown Creek Wastewater Treatment Plant’s fence line.
Directly to the west is the former DSNY Maritime Waste Transfer station, to the east is the home of Allocco Recycling. Sharp eyes will notice the Newtown Creek Alliance Living Dock project bobbing around in the water at the eastern, or left side of the shot.

A fairly uncommon view of the sewer plant, with its iconic stainless steel digester eggs dominating the shot. These eggs process “thickened sludge” using biological processes. What comes out of them has been effectively sterilized by the micro organisms which are cultivated and maintained within, but the process does generate several waste products along the way. Within, a material called “Struvite” collects on the hard surfaces which requires the DEP to perform maintenance at regular intervals to scrape the stuff away.

Another byproduct of the digester process are mephitic gases. The four Venturi jet structures you see at the left side of the image above are the exhaust pipes for the process, and the mephitic gas they are designed to handle is Methane, which is burned off. When the system first came online, the Methane flames were the characteristic bright blue turning to orange that anyone with a domestic stove is familiar with. Passerby on the Long Island Expressway who saw the flames would regularly call 911 to report a fire occurring at the plant. The DEP responded by “tuning” the speed and temperature of the Venturi structures to render the flames invisible.

The largest point source of greenhouse gases on the Brooklyn side of the Newtown Creek, these jets produce an invisible flame whose only visual cue is the diffraction of light. The DEP has famously entered into a contract with the National Grid corporation, which will harvest the Methane currently being burnt off. National Grid will use the Methane to augment their “Natural Gas” network, selling it to their customers.
The Invisible Flame, btw, is an analogy used in Islamic mysticism when referring to a supranatural race of mischievous or malign spirits whom they call the Djinn. Western Europeans use the term “Demon” for the Djinn.

Over in DUGABO…

Last Saturday, whilst wandering about in between snow storms, this outfall was spotted pouring into Newtown Creek. This is the terminus of Greenpoint Avenue alongside the Bridge, a lane which was coincidentally the path of an earlier Greenpoint Avenue Bridge – one that allowed rail to cross over from the LIRR tracks in Queens – which is today a fairly abandoned spot. The water is snow melt, incidentally.

There’s street drains all over the place which bear the screed “drains directly into waterways” and this is what it looks like when they do. The drain in question is actually visible, as is the melting snow pack which is feeding it. Along with the melt water, it’s carrying road salt and as well as all the litter and junk which line the curbs. The frustrating part of this scene is that the brand spanking new Newtown Creek Waste Water Treatment plant is just a block away and that this drain isn’t connected to it.

Amongst the many interesting people I’ve met along the Newtown Creek, some of them work for the so called “potentially responsible parties” named as being responsible for the cleanup in the Superfund agreement. Over and over, these folks have pointed out that the ongoing “point source” situation that these outfalls maintained by the City DEP present makes their court mandated mission a fools errand. You can remove the Black Mayonnaise, which is the colloquial term for the historic pollution that forms the sediment bed of the Creek, but without addressing the antiquated sewer system it won’t be twenty years before the Newtown Creek is again lined with toxic junk.

Just a short one today, but… Sludge Boat, baby, Sludge Boat!
– photo by Mitch Waxman
Last week, while on a ferry to Red Hook, (long story) the Port Richmond Sludge Boat was spotted. You might recall a recent post which described the christening and official launch of the three new exemplars of the NYC DEP’s sludge collection vessels, but if you don’t – here’s a link to a 2014 Newtown Pentacle post that discusses it. Long time readers know that I’m a bit obsessed with sludge boats, for some reason.
These boats are “MV’s” or municipal vehicles, which means that you and I own them. They are ours. Now if only DEP would lend me the keys.

All three examples of this new class were designed with Newtown Creek in mind, as this kind of MV’s can pass under the Pulaski Bridge at high tide, without requiring the drawbridge to open. Gross tonnage is 2,772 on these vessels, they’re 290 feet long with a draught of 4.3m. There’s three of them operating in NY Harbor now – Hunts Point, Rockaway, and as pictured above Port Richmond.

Sludge Boats, baby, Sludge Boats…

For those two weeks which formed the end of November, a humble narrator was enjoying a vacation from all things with the Missus. In fact, for about half of our vacation time, Our Lady of the Pentacle and myself weren’t even on the North American continent. The week of Thanksgiving, we were back, but maintained a low profile.
One thing which drew me and the camera out of our splendid seclusion, however, was the news that the NYC DEP would be holding a ceremony to christen the fleet of three new sludge boats over at their Wards Island facility. How could I resist… I mean… Sludge Boats.

MV’s (municipal vehicles) Rockaway, Port Richmond, and Hunts Point have been shaking down in NY Harbor all year. Remember, back in the beginning of 2014, when a humble narrator braved the chill climes of a polar vortex at the Brooklyn Navy Yard to bring you images of Hunts Point?
You’ll say “jump” and I’ll say “how high” when the subject of Sludge Boats is at hand. Height is what these boats are designed around, incidentally. This new class of MV’s can pass under the Pulaski Bridge, spanning my beloved Newtown Creek at high tide, without requiring the drawbridge to open.

The lady in the center of the shot is DEP Commissioner Emily Lloyd, incidentally, with Deputy Commissioner Angella Locata to her left. I don’t know who the lady on the right is, but I led this post off with her christening the Hunts Point, so there you are.
There were lots and lots of important folks at Wards Island – brass from DEP and City Hall, Press, even a press Helicopter – as well as a whole gaggle of us from the Newtown Creek Monitoring Committee. NCMC is a community group that performs citizen oversight on the multi billion dollar construction efforts at the Newtown Creek Waste Water Treatment Plant over in Greenpoint, and the delivery of these three new Sludge Boats are a sign that the decades long project is nearing completion.

After the ceremonial events were accomplished, the DEP welcomed all onboard the Hunts Point, allowing an opportunity for inspection and observation.
The Port Richmond peeled out of the dock early, probably because it had “shit to do.” Get it? Shit to do? Sludge Boat… Shit… Ahhh, nevermind. Port Richmond headed south toward the Triborough Bridge through the Hells Gate section of the estimable East River.

Exploration of the boat brought me to the big chair up on the bridge, and although no one would have let me start the engine and put Hunts Point through her paces, I did stand there murmuring “vroom vroom” until such time as I was asked to stop doing so. I did manage to say “make it so” and “ahead warp factor 3, Mr. Sulu” as well. One thinks that being so close to the very locus of Robert Moses’s power base on Wards Island causes odd concatenations in the thought process.
Alternatively, actually getting on a Sludge Boat after all these years simply made me giddy with delight. A big Mazel Tov goes out to the NYC DEP on the occasion of the birth of their new triplets.

greatest suddenness
Vas doin on English Kills, boychik, mit the bubbles?
– photo by Mitch Waxman
DUMABO. Down Under the Metropolitan Bridge Onramp, is a spot that bisects the pathway of the so called “industrial Canals of Brooklyn” or English Kills. The darkest thicket of the troubled Newtown Creek, English Kills is largely isolated from casual perusal by the electorate by a continuous shield wall of industrial buildings, which means that what happens on the water is usually commented on by an unlucky few such as myself. The engineered path that the water flows through follows the Brooklyn street grid, which creates a series of right angle turns that impede the tidal actions of the East River which is some 3 miles from here.
This adherence to the street grid, and the hydrological issues it introduces, has caused huge accretions of the so called “Black Mayonnaise” sediments to agglutinate. This sedimentation, along with the summer heat, causes the water to be “anoxic,” meaning that it often carries little or no dissolved oxygen. This kills off any aquatic life that may have wandered back here, and promulgates the colonies of sewage bacteria in the water whose aromatic exhalations remind one of rotting chicken eggs.
The sewage bacteria is provided by the many CSO’s (Combined Sewer Outfalls) found along the waterway.

To combat these anoxic conditions, the ever reliable NYC DEP (in concert with the state DEC) have installed an aeration system. Basically a giant pipe through which pressurized air is pumped, the thing operates in the same manner as a bubble wand on your aquarium fish tank. Disturbing the surface allows atmospheric gases like oxygen to become dissolved in the water. The DEP building you’ll notice on Metropolitan Avenue in East Williamsburg that adjoins the Metropolitan Avenue Bridge contains the air compressors.
It all sounds rather logical, as the efforts of engineers often do. Problem is that the sewage bacteria conditions are being caused by the Combined Sewer Outfalls on English Kills, which the DEP engineers are not focusing on. It’s sort of like shitting in a fish tank every day, and attaching more and more aerating bubble wands to combat the conditions being caused, without doing anything about… y’know, not shitting in your aquarium.

Here’s the problem – my pals over at Riverkeeper have voiced MAJOR concerns about this system, and cite a study by M. Elias Dueker which shows that bacterial fauna from English Kills are provided with an opportunity to enter the air via this system. A “Culturable Bacterial Aerosol” as they describe it, is allowed purchase into the atmosphere.
Said organisms can then find a home on any friendly terrestrial surface.
In effect, these bubbles provide a ladder for the worst pathogens in the Newtown creek watershed an opportunity to get up and out of the water. Keeping this sort of bacteria away from the general populace is sort of the mission of the DEP, btw.
from riverkeeper.org
Riverkeeper raised concerns when the city proposed aerating the rest of the creek last spring and asked the DEP to test for pathogens and sewage associated bacteria in the air, which they did not agree to do. Aeration creates bubbles on the water’s surface and is a Band Aid solution to the underlying serious problem of combined sewage overflows. Low oxygen conditions in the creek occur due to sewage contamination and although aeration increases the oxygen level in the water, it does not reduce the amount of sewage or sewage associated bacteria that are dumped into the creek. Riverkeeper has argued that aeration is an ineffective way of addressing the pollution problem and the recent study suggests that it may also negatively impact local air-quality.

Worse still, the aeration system performs its job quite well. Dissolved oxygen levels in English Kills are higher than they used to be. Accordingly, the DEP is planning on expanding the system from English Kills all the way to the Greenpoint Avenue Bridge, more than a mile away.
The pipes are planned to follow the contour of the Queens coastline, of course, because you wouldn’t be able to get away with doing it on the Brooklyn side. This puts Maspeth, and parts of Sunnyside and Blissville, in the path of the pestilent wind which would rise from the loathsome Newtown Creek.
