Almost any effective CSO mitigation plan that the city can possibly come up with will involve the creation of large multi-billion dollar retaining tanks and force our water/sewer rates to skyrocket. So here comes our out of the box thinking: How can we mitigate the negative effects of CSO without spending billions of dollars restructuring our sewer system?
The Citizens Action Committee (CAC), made up of industry experts, recommended that the city use water and sewer rates to incentivize owners to retain water on site. Currently, New York property owners do not pay to dump stormwater but by levying such charges the city can effectively incentivize owners to retain water on site and eliminate CSO occurrences, as the CAC recommended. More importantly, the administrative costs to the city would be minuscule compared to the billions that would be spent building huge tanks. As a bonus, on site retention can also have other environmental benefits (for example, green roofs mitigate the effects of urban heat island).
In recognition of the above, the mayor’s PLANYC Sustainable Stormwater Management Plan 2008, Initiative 10 states:
The City’s current water rate structure is comprised of a charge for consumption of water and an additional 159 percent for all sewer, stormwater, and wastewater services. Because this rate structure fails to reflect the true costs of stormwater generation and can lead to distortions, the City is currently undertaking a yearlong study to consider improvements. The City is analyzing its current expenditures, reviewing the rate and credit programs of other municipal water systems, and estimating the impacts of alternative stormwater rate structures on ratepayers and revenues. This effort will be coordinated with other ongoing efforts to map impervious areas in the City and to overhaul the program for water bills.
The “yearlong study to consider improvements” that the plan refers to is Booz Allen Hamilton’s (BAH) rate study, the results of which were released last week. (You may remember BAH from many of the other studies they performed for the DEP in the past. They are, after all, the DEP’s favorite go-to accounting firm when using the Water Board to bypass the contract bidding process.) The first thing worth mentioning is that this “yearlong study” took more than a year. Shocker.
But that’s not as important as the results. So let’s look at the results. The DEP paid BAH over a million dollars to “[analyze] its current expenditures, [review] the rate and credit programs of other municipal water systems, and [estimate] the impacts of alternative stormwater rate structures on ratepayers and revenues.” I would have thought that BAH would calculate the administrative costs involved and the feasibility of enacting a stormwater fee. Then they would project the savings as a result of on site stormwater retention and avoidance of the creation of stormwater retention facilities. I expected graphs indicating the relationship between the different possible stormwater rates and expected consumer response. (If we charge 5% of the water rate we need $2 million to implement the program but it’ll take us 20 years to recover that two million. If we charge 30% of the water rate we need $2 million to implement the program and we’ll recover the costs in less than a year. Something like that.) In short, how large (or small) a fee would you have to implement to start seeing a savings.
What BAH did instead was what every college student does when the deadline is up and they haven’t done any of their work. They reiterated the question. Don’t get me wrong–they did it well. They included five pages of meaningless charts (fancy, but meaningless) showing which cities use which rate structures. But they didn’t address the crux of the problem. There is nothing in the report about the effectiveness of such a program, what it would cost the DEP to implement it and how much can be saved by stormwater avoidance.
The only thing BAH actually put forth in their conclusions (slide 30 of this presentation) is the following: “New billing system must be in place in order to fully implement a City-wide stormwater rate structure and credit program.” It’s subtle. Did you catch it? It sounds to me like BAH’s pitch to sell the DEP a new rate program, one that would no doubt take another few years and another few million dollars.
In summary, we hope that the good people at the DEP and the Water Board go ahead with stormwater rates and are not put off by the BAH report. To quote the mayor’s office in Appendix K to the Sustainable Stormwater Management Plan, Environmental Entrepreneurs, a national community of over 850 prominent business leaders who believe in protecting the environment while building economic prosperity, had the following to say about stormwater rates:
We strongly urge the City to include in the Plan a firm commitment to restructure the water rates to implement a separate stormwater fee, varying based on the imperviousness of a site, as soon as possible. We understand that a rate restructuring study is now underway and urge that the consultants conducting that study be asked not whether a separate stormwater fee is practicable – because we know it is, based on the experience of many jurisdictions around the country – but rather how to implement such a fee structure in New York City as soon as possible.
Again, special thanks to the good folks at SWIM for fighting for this one. We’ve even heard DEP Deputy Commissioner of Environmental Planning and Analysis Angela Licata advocating for stormwater fees at a few Water Board hearings.
