- How Should A Wastewater Treatment Plant's Capacity Be Determined? --A
court has determined that a wastewater treatment plant's total hydraulic
flow, rather than its organic loading, should be used to calculate population
equivalents (P.E.) in setting effluent limits under an NPDES discharge
permit. Village of Fox River Grove v. Pollution Control Board, 702 N.E.
2d 656 (Ill. App. 2d Dist. 1998).
A Village's wastewater treatment plant originally was constructed in 1926. The tributary collection system allows more than "normal" inflow and infiltration (I/I), according to the court. When the plant was upgraded in 1977-78, it was decided to treat the excess flow rather than reduce it. Thus, the upgraded facility was rated at a design hydraulic flow of 1.25 million gallons per day (mgd), but a design organic flow of only 1.0 mgd. The first NPDES permit, issued in 1977, provided for effluent limitations of 30 mg/l BOD, and 30 mg/l suspended solids. In 1986, the Illinois Environmental Protection Agency (EPA) proposed a new NPDES permit (National Pollutant Discharge Elimination System) reducing the limits to 20 mg/l BOD, and 25 mg/l suspended solids. The Village objected on the ground that the state regulations required the more stringent limits only for untreated waste loads of 10,000 P.E. or more. The Village pointed out that its plant design was for untreated waste loads up to 10,000 P.E. and that the present loading was under that level. The Village and the Illinois EPA compromised. The plant was re-rated at a 9,900 P.E. design organic load and an NPDES permit was issued at 30/30. In 1992, the permit was renewed at 25 mg/l CBOD, and 30 mg/l suspended solids. In 1996, the Illinois EPA issued a draft NPDES permit with a more stringent level of 20 mg/l for CBOD5. It explained that, although the plant was re-rated at 9,900 P.E. organic load, it is hydraulically rated at 12,500 P.E. (based on 1 P.E. being the equivalent of 100 gallons of "sewage" per day). Thus, the agency rated the plant at 1.25 mgd, with the resulting more stringent effluent limits. The Village argued that the term "untreated waste load" used in the regulation dictating effluent limits means the amount of wastewater a plant is designed to treat, not the total flow to the plant. Therefore, the Village urged, it was an error to use hydraulic capacity instead of organic loading to calculate "untreated waste load." The court disagreed. It found that, in setting effluent limits in an NPDES permit, it is the impact on the treatment plant that must be measured, not the impact on the stream. The court continued, the regulation provides that the impact on the plant is to be measured by the highest of three specified parameters, which is the flow of sewage at 100 gallons per day. "The facility in this case is designed to process 1.25 million gallons per day. Therefore, the impact would be measured at 12,500 P.E., which would then require the facility to adhere to the stricter standard." Id. at 663. The Village argued that since the influent comprises both "sewage" and inflow/infiltration, the organic rating should be used to determine "flow of sewage." The court rejected this assertion: "[A]s a practical matter, once the sewage becomes mixed with the groundwater and storm water, the resulting product is all sewage." Id. Therefore, it concluded, the hydraulic loading correctly was used. Finally, the Village argued there was no evidence that the untreated waste load ever reached 10,000 P.E. or more. Therefore, the higher standard should not be applied. The court responded by saying that there are likely to be more frequent fluctuations in "actual sewage flowing into the facility rather than in the total amount of water, since the facility is designed to process only 1.25 million gallons of water per day." Id. at 664. Thus, it concluded, it was more reasonable to use the hydraulic rating. It agreed that "untreated waste load" means total load. Putting aside any debate over the court's reasoning, it must be remembered that courts generally give deference to an agency's interpretation of its own regulations, provided there is no issue of inconsistency or plain error. One "lesson" from this case could be the "balancing" that should occur in dealing with excess inflow and infiltration. Is it more cost-effective to try to reduce I/I or to treat the flows at the plant? It also must be borne in mind that high I/I flows have the potential to "wash out" biological processes at a plant, possibly making consistent compliance with effluent or water quality parameters difficult. A second question arises as to how the capacity of a plant is to be measured from the standpoint of permitting new customer connections. This is both a regulator and an owner issue. If the plant is to be rated at 12,500 P.E., will connections be allowed up to that level? If actual connections provide less than 100 gallons per day per person, can more connections be permitted? If I/I is reduced, should the permit be modified? Source: February 11, 1999, Water Online, by Daniel J. Kucera. Also see: Florence Sewage Spills |

- Fuel additive turns up in reservoir water -- South Lake Tahoe,
Calif. -- A controversial gasoline additive that has been showing up in
Lake Tahoe-area water supplies has been detected at a reservoir 30 miles
away.
Area ranchers are worried about the discovery of MTBE, developed in the 1970s to allow fuel to burn cleanly, at the reservoir in Alpine County. thirteen drinking wells in South Lake Tahoe have been shut down after being contaminated or threatened with contamination. In California, MTBE has contaminated more than 10,000 groundwater sites. The MTBE comes from leaking gasoline storage tanks in the area. The additive was designed to reduce air pollution, but scientists now suspect it is a carcinogen. It apparently amde its way to the reservoir through South Lake Tahoe's wastewater export system.

- Anti-SLAPP Suit Legislation -- The Oregon Land Conservation
and Development Commission (LCDC) will introduce Senate Bill 330 in the
1999 Legislation Session. The purpose of SB 330 is to protect Oregon citizens
from Strategic Lawsuits Against Public Participation (SLAPP suits).
The legislation is being introduced at the request of Oregon Communities for a Voice in Annexations (OCVA), the Department of Land Conservation and Development, a number of elected officials, 1000 Friends of Oregon, the League of Women Voters, and other citizen advocacy groups around Oregon. SB 330 (LC 798) was prompted primarily by complaints of retaliation in the form of lawsuits - or threats of lawsuits - by development interests against citizens who have spoken out on public policy issues, especially those related to growth. SLAPP suits have also been used as weapons in school curricula, consumer protection, environmental and other public policy debates. Nine other states have recently passed anti-SLAPP legislation. Citing Indiana’s anti-SLAPP law, Charlotte Robertson of the Hoosier Environmental Council said, “The legislature wisely recognized the threat to our first amendment rights and passed this measure as an emergency act.” Vanderbilt University’s Freedom Forum feels SLAPPs are one of the most serious threats to free speech and an open democratic process. OCVA provided DLCD with written testimony from dozens of its members documenting what OCVA Chairman Jeff Lamb called “this form of legal and financial terrorism.” Lamb also said, “the purpose of SLAPPs is to silence the public through intimidation and the threat of losing one’s home, business, assets and financial security. Through SB 330, Goal #1 - citizen involvement - is being protected by the very agency chartered to do just that.” SB 330 (The Citizen Participation In Government Act of 1999) provides that “a person is not civilly liable for any statement made by the person in the course of participating in an administrative, quasi-judicial or legislative proceeding conducted by a public body.” It also provides for the recovery of “reasonable attorney’s fees” and other expenses.
