Memo/Review of Henn. Co Proposal Temp. Store Incinerator Ash08/03/1989 14 :28 DOHERTY RUMBLE & BUTLER f a � MEMORANDUM 612 291 9313 P.09 TO: City of Hopkins Planning Commission and City Council ?/embers FRONT; Dick Nowlin, Doherty Rumble & Butler, P.A. DAM July 26, 1989 RE: Review of Hennepih County Proposal to Temporarily Store Incinerator Ash at the Hennepin County Public Works Facility in Hopkins Hennepin County has proposed to store up to 20,000 tons of ash produced at the Minneapolis Incinerator (the incinerator) in a; storage building currently used for storing salt on its Publlic Works Facility Site in Hopkins (the Proposal). The Proposal is now being reviewed by the Minnesota Pollution Control Agency (MPCA) and the Metropolitan Council for purposes of issuing a temporary ash storage permit to Hennepin County. Question has arisen as to the City of Hopkins' review respDnsibility and authority with respect to the Proposal. This memo is written to provide background and comments regarding the legal. framework applicable to the City's review. It has been written with assistance from City staff. I. GENERAL BACKGROUND Hennepin County indicated at that the Metropolitan Council's Environmental Committee Hearing on July 19th that it began developing the Proposal in early July because of delays experienced in securing authorization to dispose of the incinerator's ash at the'Woodlake Landfill in Medina. BFI is requesting the issuance of Type I and Type II Ash Storage Permits for he incinerator's ash at the Woodlake Landfill. These 08/03/1989 14:29 DOHERTY RUMBLE & BUTLER 612 291 9313 P.10 applications have been in process since February, 1989 and have thus far only received Planning Commission review. County staff indiicated that the earliest a Type I Permit could be issued would be November. The County indicated that they were also discussing the !possibility of disposing the ash outside the Metropolitan Area with Olmsted County which has an Ash Disposal Facility in Dodge County. Dodge County has now vetoed this alternative. It is extremely difficult to predict the date by which thelWoodlake Ash Storage Permit will be issued due to the numerous opportunities for delay built into the State and local permitting process. Both the environmental review process and theIMPCA permitting process together with litigation could delay ash !disposal at Woodlake by more than a year beyond the November 1989' target date. A Contested Case Hearing Request on the permit has !already been received by the MPCA for the Woodlake proposal. If the MPCA Board were to order a contested case hearing, a one year delay could be experienced in securing either the Type I or Type II Storage Facility Permits. The MPCA's regulatory program vis -a -vis incinerator ash disposal is currently being developed. A law was passed in 1988, Minn;. Stat. §115A.97, which classed incinerator ash as a "special waste" and required the preparation of regulations for ash disposal management by June 30, 1990. A temporary regulatory program governing ash storage was approved by the MPCA in Septjember, 1988. This program authorizes the issuance of Type I and !Type II Storage Permits. A Type I Permit is a temporary storage authorization which requires the removal of ash from the 2. 0$/03/1989 14:29 DOHERTY RUMBLE & BUTLER 612 291 9313 P.11 permitted location within a specific time frame. A Type II Permit: requires storage at a facility constructed with a liner andleachate collection system. These facilities could become permanent disposal locations. The proposed storage in the Public Works Building in Hopkins will involve the issuance of a Type I Storage Permit. II. GENERAL MUNICIPAL AUTHORITY Though solid and hazardous waste treatment, storage and disOosal facilities are subject to extensive State and, in some instances Federal regulation, whether temporary or permanent in nature, these facilities also can be subject to local (municipal andicounty) land use and environmental regulatory controls. Minnesota law does not pre - empt local regulation of these facilities, and as a result, such facilities are subject to the normal land use regulatory powers authorized by the Municipal Planning Act including zoning ordinances. As with other facilities which are regulated by both State agencies and local authorities, the regulatory interaction is governed by certain common law principals. Local permit provisions governing state regulated facilities cannot conflict with the state regulatory and permit provisions. An Attorney General's opinion discussing the !Conflict principal in relation to a landfill is attached as Appekdix I. Local authority, vis -a -vis the regulation of waste facilities was recently reaffirmed by the Minnesota Court of Appeals in the case of Peter Sherner, et al, v. Ambrose Culliton, et al., 382 N.W. 2d, 562 (Minn.app. 1986) which sustained the power of a township to preclude the disposal of sewage sludge 3. 0p/03/1989 14:30 DOHERTY RUMBLE & BUTLER 612 291 9313 P.12 within its jurisdiction. This opinion is also attached. Because of this legal context, the City of Hopkins has the authority and responsibility to review Hennepin County's proposal in relation to tfhe provisions of its zoning ordinance and other official controls. III. CHARACTERIZATION OF THE PROPOSAL To determine the type of local review which must be performed in relation to the Proposal, it must be characterized oz defined Characterization clearly depends on the facts and impacts associated with the proposal, some of which are at this point unknown. As a result the following discussion is somewhat tentiative and is based on current information. Special Waste Both Federal and State legislators and regulatory authorities have been for some time in a quandary as to how to classify incinerator ash in relation to solid and hazardous waste treatment, storage, and disposal rules. Some incinerator ash from certain facilities has been tested to be a hazardous waste under leachate toxicity tests. Generally, this ash has contained relatively large concentrations of heavy metals (lead and cadmium) as well as other contaminents. It is also generally established that fly ash exhibits more toxicity characteristics than does bottom ash. Incinerator proponents and others, however, have questioned the legitimacy of the 4. 08/03/1989 14 :31 DOHERTY RUMBLE & BUTLER i b. 612 291 9313 P.13 various testing measures used for incinerator ash. Thus far, ash has not been officially characterized as a hazardous waste. As mentioned, Minnesota, by law, treats incinerator ash as a special waste which is neither a hazardous nor solid waste for the purpose of applying treatment, storage, and disposal regulatory requirements. "Waste Facility "? There is a legitimate question as to whether the temporary storage of incinerator ash within a building is a "waste facility ". The City's zoning ordinance provides no definition of "waste facility." "Waste facility" in common terminology would imply some sort of permanent facility designed exclusively for the storage or disposal of ash. The primary state definition of "waste facility" is contained in Minn. Stat. §115A.03, subd. 35 and reads as follows: "Waste facility means all property, read, or personal, including negative and positive easements and water and air rights, which is or may be needed or useful for the processing or disposal of waste, except property for the collection of the waste and property used 5. 08/03/1989 14 :31 DOHERTY RUMBLE & BUTLER 612 291 9313 P.14 primarily for the manufacture of scrap metal or paper. Waste facility includes but is not limited to transfer stations, processing facilities, and disposal sites and facilities." Since this definition references treatment and disposal (not storage) facilities, and includes facilities of a permanent nature, it could be concluded that the temporary ash storage site is not a "waste facility" for purposes of the City's zoning ordinance. c. Temporary Storage Site Regardless of how long Hennepin County has to store the ash at this location, it must under MPCA's existing procedures and new regulations, eventually be removed and placed elsewhere. The ash disposal procedures currently in existence and those being developed require a lined facility, and a leachate collection system to capture any liquids emanating from the waste deposit. The Hennepin County Garage is lined only by an asphalt pad and will have no leachate collection system. As a result it can never be a permanent storage site. IV. ENVIRQNMENTAL REVIEW REQUIREMENTS Whether an EIS or an EAW needs to be prepared for the 6. • • 0p/03/1989 14:32 DOHERTY RUMBLE a BUTLER 7. 612 291 9313 P.15 Proposal depends on its characterization and the application of M Rules Pts. 4410.0200 to 4410.5600. A review of Minn. Rules Pt. 4410.4300 dealing with mandatory EAWs, including the provisions relating to storage facilities, hazardous waste and solid waste, indicates that a temporary storage facility for incinerator ash does not fall wittiin any of the categories for which a mandatory EAW is required. An EAW is mandatory for "mixed municipal solid waste energy recovery facility ash landfill" (See subp. 17G), but the Hennepin County Garage is not a landfill. A review of Minn. Rules Pt. 4410.4400 (mandatory EIS), including provisions relating to solid and hazardous waste, indicates that a temporary storage facility for incinerator ash doe4 not fall within any of the categories for which a mandatory EISIis required. The proposal, however, does not fall within any of the exerdptions to EIS /EAW preparation requirements contained in Minn. Rules Pt. 4410.4600 except if it could be said to be a "minor temporary use of land having negligible or no permanent effect on theienvironment ". (See subp. 22.C.) As a result, the City has the authority to determine whether a discretionary EAW should be prepared for the proposal since Minn. Rules Pt. 4410.4500 provides that: "A governmental unit with jurisdiction may order the preparation of an EAW for any project that does not exceed the mandatory thresholds designated in Pt. 4410.4300 or 4410.4400. If a governmental unit determines that because 08/03/r9e 14:32 DOHERTY RUMBLE & BUTLER 612 291 9313 P.16 of the nature or location of the proposed project the project may have the potential for significant environmental effects, and the project is not exempted pursuant to Pt. 4410.4600." V. ZONING BACKGROUND Zoning treatment of the Proposal depends on its location and characteristics, applicable zoning provisions and determinations vis-a-vis discretionary interpretations by the City Council, Zoning Administrator and City Attorney. The Hennepin County proposal is located in an 1-2 Dis Section 540.0 the Zoning Ordinance does not list temporary ash or waste storage as a permitted use. It does authorize chemical and allied products, petroleum storage, and building materials yards as permitted uses. Likewise, a temporary ash storage facility is not listed as a conditional use in the Z Districts under Section 540.03 though "public utility structures" and "junk yards" are listed as potential conditional uses. It also does not appear that a temporary ash storage facility is a permitted accessory use under Section 540.05. Item (d) of that section defines accessory uses to include "incidental use customary in the operation of permitted or conditional user" Since ash storage is incidental to an incinerator and sinde incinerators are not permitted within the District, it wound not appear that this temporary storage proposal would fall within that language. 8. 08(03/1989 14.33 DOHERTY RUMBLE & BUTLER 612 291 9313 P.17 In summary, it would appear that the Proposal could be dealt with under Section 525.13, Subd. 1 which authorizes the clagsification of an unlisted but similar use as a conditional use in a specific district. Waste disposal facilities in other jur are typically authorized by the issuance of a conditional or special use permit. Conditional and special use perr have been utilized elsewhere because of concern about the MPC1}.s lack of attention to local land use impacts from these facilities as well as the inability to secure prompt and efficient enforcement action from the MPCA. Conditional and 1 special use permits provide the situs jurisdiction with more speOific protections vis -a -vis adverse land use impacts and provide local enforcement opportunities should anything go awry. Hennepin County's Proposal could be addressed by some mechanism other than a special or conditional use permit. On the 1 other hand, given the temporary but relatively unknown duration of the storage operation as well as its potential effects, it would appear appropriate to develop a conditional use permit applicable for the Proposal. Another option for the City was created by the 1989 Legislature. Minn. Laws 1989, Chapter 200 now authorizes the establishment of "interim uses" under the Municipal Planning Act; An "interim use" is defined as a "temporary use of property until a particular date, until the occurrence of a particular event, or until zoning regulations no longer permit it." Minn. Statf. 5462.3597. This alternative is a variation on a conditional use permit and was enacted specifically to address 9. • 08/03/1989 14:34 DOHERTY RUMBLE & BUTLER t theisituation where a city wants to limit the duration of a particular temporary use Hennepin County comrnittment and the City's concern about the length of storage authorization, it would be appropriate for the City to classify the temporary ash storage facility as an interim use in the I -2 District. A copy of chapter 200 is attached. Encliosures FDNngem10 0 F.D.N. 10. 612 291 9313 P.18
