For activities that may affect historic properties listed in, or eligible for listing in. the National Register of Historic Places, the notification must state which historic property may be affccted by the proposed work or include a vicinity map indicating thc location of the historic property. 13. N otifieation. (a) Timing; where required by the terms of the NWP or RGP category, thc prospcctive permittee must notify the District Engineer with a preconstruction notification (PCN) as early as possible. The District Engineer must detennine if the notification is complete within 30 days of the date ofreceipt and can request additional information necessary to make the PCN complete only once. However, if the prospective permittee does not pro:vide all of the requested information, then the District Engineer will notify the prospective permittee that the notification is still incomplete and the PCN review process will not commencc until all of the requested information has been received by the District Engineer. The prospective permittee shall not begin the activity: (1) Until notified in writing by the District Engineer that the activity may proceed under the NWP or RGP category with any special conditions imposed by the District or . Division Engineer; or (2) If notified in writing hy the District or Division Engineer that an Individual Permit is required; or , (3) Unless 45 days bave passed from the District Engineer's receipt' ofthe complete notification and the prospective permittee has not received written notice from the District or Division Engineer. Subsequently, the permittee's right to proc""u UTI<1"r the NWP or RGP category may be modified, suspended, or revoked only in accordance with the procedure set forth in 33 CFR 330.5(d)(2). (b) Contents of Notification: The notification must be ill writing anu include the following information: (1) Name, address and telephone numbers of the prospective permittee; (2) Location ofthe proposed project; (3) Brief description of the proposed project; the project's purpose; direct and indirect adverse environmental effccts the project would cause; any other NWP(s), Regional General Permit(s), or Individual Perrnit(s) used or intended to be used to authorize any .part ofthe proposed project or any related activity_ Sketches should be provided when ncccssary to show that the activity complies with the terms of the NWP or RGP category (Sketches usually clarify the project and when provided result in a quicker decision.); Corps No. 2006-13 7 Page 3 005 Enclosure (3) 09/08/2007 SAT 10:29 FAX 541 687 0739 GOEBEL ENGINEERING ~017/031 . . (10) For NWP 31 (Maintenance of Existing Flood Control Facilities), the prospective permittee must either notify the District Engineer with a PCN prior to each maintenance activity or submil a five year (or less) maintenance plan. In addition, the PCN must include all of the following: (i) Sufficicnt baseline information identifying tile approved channel depths and configurations and existing facilities. Minor deviations are authorized, provided the approved flood control protection or drainage is not increased; (ii) A delineation of any affected special aquatic sites, includltlg wetlands; and, (iii) Location o[(he dredged material disposal site; (11) For NWP 33 (Temporary Constrllction, Access, and Dewalering), the PCN must also include a restoration plan of reasonable measures to avoid and minimize adverse effects to aquatic resources; (12) For NWPs 39, 43 and 44, and RGP category K, the PCN must also include a written statement to the District Engineer explaining how avoidance and minimization for losses of waters of the US were achieved on thc:project site; (13) For RGP l;:ategory K and NWP 42, the PCN must include a compensatory mitigation proposal to offset losses of waters oftheUS or justification explaining why compensatory mitigation should not be required. For discharges that cause the Joss of greater thatl 300 linear feet of an intermittent strt:am bed, lo be aulhori:!ed, the Dislrict Engineer must determine that the activity complies with the other terms and conditions of the NWP or RGP category, determine adverse environmental effects are minimal both individually atld cumulatively, atld waive the limitation on' stream impacts in writing before the permittec may proceed; (14) For NWP 40 (Agricultural Activities), the peN must include a compensatory mitigation proposal to offset losses of waters of the US. This NWP docs not authorize the relocation of greater than 300 linear-feet of existing serviceable drainage ditches constructed in non-tidal streams unless, for drainage ditches constructed in intermittent non-tidal streams, the District Engineer waives this criterion in writing, and the Distrkt Engineer has determined that the project complies with all temlS and conditions of this NWP, and that any adverse impacts of the project on the aquatic environment are minimal, both individually and cu.muJatively; (15) For NWP 43 (Stunnwater Managemenl Facililie.), the PCN must include, [ur the construction of ncw stormwatcr management facilities, a maintenance plan (in accordance with state and local requirements, if applicable) atld a compensatory mitigationproposaJ to offset losses of waters of the US. For discharges that cause the loss of greater than 300 [in ear feet of an intermittent stream bed, to be authoriz.ed, the District Engineer must determine thal the activity complies with the other terms atld conditions of the NWP, determine adverse environmental effects are minimal both individually and cumulativcly, and waive the limitation on strcam impacts in writing before the permittee may proceed; Corps No. 2006-13 7 Page 5 of 15 Enclosure (3) 09/08/2007 SAT 10:29 FAX 541 687 0739 GOEBEL ENGINEERING 141 018/031 . . If the District Engineer delermines that the adverse cffects of the proposed work are more than minimal, then the District Engineer will notifY the applicant either: (I) That the proj ect does not qualify for authorization under the NWP or RGP and instruct the applicant on the procedures to seek authorization under an Individual Permit; (2) that the project is authorized under the NWP or RGP subject to the applicant's submission of a mitigation proposal that would reducc the adverse effects on the 3;quatic environment to the minimal level; Of (3) that the project is aulhorized und"f the NWP or RGP with specific modifications or conditions. Where the District Engineer detennines that mitigation is required to ensure no more than minimal adverse effects occur to the aquatic environment, the activity will be authorized within the 45-day PCN period. The authorization will includc the necess<IIY conceptual or specific mitigation or a requirement that the applicant submit a mitigation proposal that would reduce the adverse effects on the aquatic environment to the minimal level. When conceptual mitigation is included, or a mitigation plan is required under item (2) above, no work in watcrs of the US will occur until the District Engineer has approved a specific mitigation plan. (e) Agency Coordination: The District Engineer will consider any comments from Federal' and state agencies concerning the proposed activity's compliance with ,the terms and conditions ofthe NWPs and RGP and the need for mitigation to reduce the proj ecl's ad verse environmental effects to a minimal level. For activities reqlliring notifkation to the District Engilieer iliatresult in the loss of greater than 1/2-acrc of waters of the US, the District Enginee~ will provide immediately (e.g., via facsimile transmission, overnight maii, or other expeditious manner) a copy to the appfOpriate Federal or state officcs (USFWS, state natural resource or water quality agency, ,EP A, State Historic Preservation Officer (SHPO), and, if appropriate, the NMFS). With the exception ofNWP 37, these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the District Engineer notice that they intend to provide substantive, site-specific co=ents. If so contacted by 'Ul agency, the District Engineer will wait an additional 15 calendar days before making a decision on the notification. The District Engineer will fully consider agency co=ents received within the specified time framc, but will provide no response to the resource agency, except as provided below. The District Engineer will indicate ill the administrative record associated with each notification that the resource agencies' concerns were considered. As required by section 305 (b)( 4 )(B) of the Magn.uson-Stevens Fi sheryConservation and Management A,f.t, thc District Engineer will provide a response to NMFS within 30 days of receipt of any Essential Fish Habital conservation recommendations. Applicants are encouraged to provide the Corps multiple copies of notifications to expedite agency notification. (1') Wetlillld Delineations: Wetland delineations must be prepared in accordance with the current method required by the Corps (For RGP category J see paragraph (b)(9)(iii) for parcels less than (1/4-acre in size). The permittec may ask the Corps to delineate the special aquatic site. There may be some delay ifthe Corps does the delineation. Furthermore, the 45-day period will not start until the wetland delineation has been completed 'and submitted to the Corps, where appropriate. Corps No. 2006-137 Page 7 of 15 Enclosure (3) 09/08/2007 SAT 10:30 FAX 541 687 0739 GOEBEL ENGINEERING I4J 019/031 . . (c) Compensatory mitigation at a minimum one-far-one ratio will be rcquired for all wet.land impacts requiring a peN, unless the District Engineer determines in writing that some other form of mitigation would be more environmentally appropriate and provides a project-specific waiver of this requirement. Consistent with National policy, the District Engineer will establish a preference for restoration of wetlands as compensatory mitigation, with preservation used only in exceptional circumstances. (d) Compensatory mitigation (Le., replacement or substitution of aquatic resources for those impacted) will not be used to increase the acreage losses allowcd by the acreage limits of some of the NWPs or RGP categories. For example, 1/4-acre of wetlands cannot be created to change a 314-acre loss ofwetJands to a 1/2~acre loss associated with RGP category K verification. However, 1/2-acre of created wetlands can be used to reduce the impacts of a 1/2-acre loss of wetlands t.o the minimum impact level in order to meet the minimal impact requirement associated with NWPs or RGP catcgorics. (e) To be practicable, the mitigation must be available and capable of being done considering costs, existing tcchnology, and logistics in light of the overall project purposes. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferably in the same watershed. (f) Compensatory mitigation plans for projects in or near streams Or other open waters will normally include a requirement for the establishment, maintenance, and legal protection (e.g., easements, deed restrictions) of vegetated buffers to open waters. In many cases, vegetated buffers will be the only compensatory mitigation requiTed. Vegetated buffers should consist of native species. The width of the vegetated buffers required will address documented water quality or aquatic habitat loss conccms. N 01111ally, the vegetated buffer will be 25 to 50 feet wide on each side of the stream, but the District Engineers may require slightly wider vegetated buffers to address documented water quality or habitat loss concerns. Where both wetlands and open waters exist On the project site, the Corps will determine the appropriate compensatory mitigation (e.g:, stream buffers or wetlands compensation) based on what is best for the aquatic environment on a watershed basis. In cases where vegetated buffers are determined to be the most appropriate form of compensatory mitigation, the District Engineer may waive or reduce the requirement to provide wetland compensatory mitiga.tion for welland impacts. (g) Compensatory mitigation proposals submitted with the "notification" may be either conceptual or detailed. If conceptual plms are approved under the verification, then the Corps will condition the verification to require detailed plans be submitted and approved by . the Corps prior to eonstruclion of the authorized activity in waters of the U.S. (h) Permittees may propose the usc ofmitigatiC]n banks, in-lieu fee arrangements or separate activity-specific compensatory mitigation. In all cases that require compensatory mitigation, the mitigation provisions will speeily the party responsible [or accomplishing and/or complying with the mitigation plan. '.

Further, such discharges may be authorized in designated critical habitat for Federally listed threatened or endangered species if the activity complies with General Condition J J and the USFWS or ,he NMFS has concurred in a determination of compliance with this condition. (b) ForNWPs 8, 10, 15,19,22,23,28,30,33,34,36,37, and 38 and RGP categories A, D, G, H, and !, notification is required in accordance with General Condition lJ, for any activity proposed in the designated critical resource waters including wetlands adj acent to those waters. The District Engineer may authori'!:e activities under these NWPs or RGP categories only after it is determined that the impacts to the critical resource waters will be no more than minimal. 26. Fills Within IOO-Year Floodplains. For purposes oftrus General Condition, IOO-ycar floodplains will be identified through the existing Federal Emergency Management Agency's (FEMA) Flood Insurance Rate Maps or FEMA-approved local floodplain maps. (a) Discharges in Floodplain; Bclow Headwaters. Discharges of dredged or fill material into waters of the US within the mapped I aD-year floodplain, below headwaters (i.e. five cfs), resulting in permanent above-grade fills, are not authorized by NWPs 40,42, 43, and 44 and RGP category K. (b) Discharges in FIoudway; Abuve H~adwat"rs. Discharges of dredged or fill material into waters of-the US within the FEMA or locally mapped tloodway, resulting in permanent above-grade fills, are not authorized by NWPs 40, 42, and 44 and RGP category K. (c) The permittee must comply with any applicable FEMA-approved state or local floodplain management requirements. 27. Construction Period. For activities that have not been verified by the Corps and the project was commenced or under contract to commence by the expiration date of the NWP or RGP category (or modification or revocation date), the work must be completed within 12.months after such date (including any modification that affects the project). For activities that have been verified and the project was commenced or under contract to commence within the verification period. the work must be completed by the date determine!! . by the Corps. For projccts that have been veritled bythc Corps, an extension ofa Corps approvcd completion date maybe requested. This request. must be submitted at least one month before t.he previously approved completion date.

The acreage ofIoss of waters of the US is the threshold measurement of the impact to existing waters for determining whether a project may qualify for an RGP; it is not a net threshold that is calculated afIer considering compensatory mitigation that may be used to offset losses of aquatic functions and values. The loss of stream bed includes the linear feet of stream bed that is filled or excavated. Impacts to ephemeral streams are not included in the liDear foot measurement of loss of slream b"d for the purpose of determining compliance with the linear foot limits ofRGP-K. Waters of the US temporarily filled, flooded, excavated, or drained, but restored to preconstruction contours and elevations after construction, are not included in the meas\lIement of loss of waters ofthe US. Non-tidal Wetland: A non-tidal wetland is a wetland (i.e., a water ofthe US) that is not subject to the ebb and flow oflidal waters. The definition of a wetland can be found at 33 CFR 3283(b). Non-tidal wetlands contiguous to tidal waters are located landward of the high tide line (i.e., spring high tide line). Open Water: An area that, during a year with normal patterns of precipitation, has standing or flo""ing water for sufficient duration to establish an ordinary high 'water mark. Aquatic vegetation within the area of standing or flowing water is ,either non-emergent, SparSc, or absent. Vegetated shallows are considered to be open waters. The term ., open water" includes rivers, streams, lakes, and ponds. For the purposes of the RGPs, this term does not include ephemeral waters. Per.,nnial Slr.,am: A p.,rennial s!ream has ilowing water year-round during a typical year. The water table is located above the stream bed for most of the year. Groundwater is the primary source of water for stream flow. Runoff from rainfall is a supplemental source of water for stream flow. Permanent Above-grade Fill: A discharge of dredged or fill material into waters ofthe US, including wetlands, that results in a substantial increase in ground elevation and permanently convcrts part or all of the waterbody to dry land. Structural fills authorized by RGP A, G, etc. are not inclUded. Presel:vation: The protection of ecologically important wetlands or other aquatic resources in perp!"tuity through the implementation of appropriate legal and physical mechanisms. Preservation may,includc protection of upland areas adjacent to wetlands as necessary to ensure protection and/or enhancement of the ovcrall aquatic ecosystem. Restoration: Rc-establishment of wetland and/or other aquatic resource characteristics and_. function(s) at a site where they have ceased to exist, or exist in a substantially degraded state. Riftle and Pool Complex: Rime and pool complexes are special aquatic sites Wlder the 404(b)(l) Guidelines. Riffle and pool complexes sometimes chamcterize steep gradient sections of strcaIns. Such stream sections are recognizable by their hydraulic characteristics, The rapid movement of water over a course substrate in riffles results in a rough flow, a turbulent surface, and high dissolved oxygen levels in the water. Pools are deeper areas associated with riffles. A slower stream velocity, a streaming flow, a smooth surface, and a finer substrate characterize pools. Single and Complete Project: The tenn "single and complete project" is defined at 33 CPR 330.2(i) as the total project proposed or accomplished by one owner/developer or partnership or other association of owners/developers (s'ee definition of independent utility). For lincar projects, the "single and campl",t., proj ect" (i.",., a single and complete crossing) ",ill apply to each crossing of a separate Corps No, 2006-137 Page 13 of 15 Enclosure (3) 09/08/2007 SAT 10:31 FAX 541 687 0739 GOEBEL ENGINEERING Ig] 022/031 . . Vegetated Shallows: Vegetatcd shallows are special aquatic sites under the 404(b)(1) Guidelines. They are areas that are permanently inundated and under normal circumstances have rooted aquatic vegetation. such as seagrasses in marine and estual;ne systems and a variety of vascular rooted plants in freshwater systems. Watcrbody; A waterbody is any area that in a normal year has water flowing or standing above ground to the extent that evidence of an ordinary high water mark is established. Wetlands contiguous to the waterbody are considered part of the waterbody. Corps No. 2006-13 7 Page 15 of 15 Enclosure (3) 09/08/2007 SAT 10:31 FAX 541 687 0739 GOEBEL ENGINEERING IaI 023/031 . .

Except as allowed in Condition 3(11) or 3(c) [below], the authorized work shall not cause turbidity of affected waters to exceed natural background turbidity by 10 percent, measured 100 feet downstream from the activity causing turbidity. b. For projects in streams where the gradient is less than or equal to two (2) percent (rise/run), monitoring shall take place at no less than four (4)-hour intervals during active in-water work Where erosion control measures specified in General Condition 4 ofthis WQC have been implemented, the turbidity standard specified in General Condition 3(a) may be exceeded for a maximum of one (1) monitoring interval per 24- hour work period. c, For projects in streams where the gradient is great than two (2) percent (rise/run), monitoring shall take place at no less than two (2)-hour intervals during active, in-water work. Where erosion control measures specified in 'General Condition 4 ofthis certification have been implemented, the turbidity standard ';peciIied in General Condition 3(a) may be exceeded for a maximum of two (2),hours. d_ For proj ects impacting streams, water quality monitoring points shall be established at an undisturbed site representing background conditions a.t least I 00. feet upstream from the point of permitted work, and at a point lOO feet downstream from the point of permitted activity in the visible plume, if one is present. Other monitoring locations may he authorized by the Corps if access is problematic. A turbidimeter is recommended for measuring; however, visual gauging is acceptable. If measured visibility, turbidity that is visible over background is considered an exceedance of the standard. e. The person(s) conducting the monitoring shall be responsihle for immediately notifying the permit holder or the permit holder's onsite r<q>resentati ve of any exeeedallce of tile-, turbidity standard and shalll(eep a record oUhe exceedanee. If a lO percent exceedance of the background level occurs at 100 feet below the project site, turbidity control measures shall be improved or additional controls shall be implemented until the turbidity standards is met. Monitoring shall continue at prescribed compliance intervals. If cxceedances caused by the permitted activity occur during two consecutive measurements, the activity causing the turbidity shall stop until appropriate abatement techniques bring the proj ect bacI{ into compliance. 4.

Site Restoration: Riparian and Wetland Vegetation Protection and Restoration-Vegetation associated with water of the State, including wetlands, is absolutely essential in preserving and enhancing water quality. In many cases this includes vegetation on adjacent upland buffer areas. Therefore riparian, wetland, and shoreline vegetation in the project area shall be protected from unauthorized disturbance, or, if authorized work results in unavoidable disturbance, shall be restored and enhanced. The applicant must protect or restore habitat access, production of habitat elements, channel conditions, flows, watershed conditions, and other ecosystem processes that form and maintain productive habitats. Preparation and implementation of a Site Restoration Plan may be required to ensure that all habitats and acccsscs.( e.g., streambanks, soils, large woody material, and vegetation) disturbed by the proj cct are restored. a. Site Restoration Plan Requirements-Consistent with OAR 141-085-0171, when impacts to existing vegetation arc anticipated as a result of the proposed activities, and the impacts will not require mitigation because they'are considered temporary, the applicant must provide a rehabilitation plan for temporary impacts which includes the following: i. Existing and proposed contours. ii. Existing physical and biological characteristics, including vegetation. iii. Geomorphology and habitat features of stream or other open waters. iv. Areas oftemporary impacts associated with construction staging and access. v, Restoration goals and objectives necessary to reslore losl functions. VI. A planting plan appropriate to the geographic area which demonstrates how the applicant will replace or enhance riparian vegetation function. vii. A plan to control exotic invasive vegetation; Vlll. An irrigation plan, including water supply source, if necessary. b. General Conditions Relatiol! to Site Disturbance. i. All exposed soils must be stabilized during a,nd after constmction to prevent erosi ons and sedimentation. ll. All disturbed areas shall be returned to original ground contours at project completion. iii. There shall be no operation of equipment such that machinery drives into the water. Work must be conducted from the top of the bank or in the dry. IV, No removal of vegetation shall occur outside the construction corridor or project footprint.

Use ofthe following design elements, while discretionary, may lead to more successful rehabilitation efforts. i. Design Considerations. These guidelines may be used to develop a design plan and to aid in restoration goal assessment. While no single element is sufficient to measure success, the intent is that these features should be present within reasonable limits of natural and management variation: (1) Bare soil spaces that approximate the size and dispersal pallern of pre- existing conditions. (2) Soil movement, such as active rills or gullies and soil disposition around plants or in small basins, is absent or slight and local; (3) If areas with past erosion are present, they are completely stabilized and healed; (4) Plant litter is well distributed and effective in protecting the soil with few or no litter dams present; (5) Native woody and herbaceous vegetation, and germination micro sites, are present and well distributed across the site; (6) Vegetation structure is resulting in rooting throughout the pre-existing, available soil profile; (7) Plants have normal, vigorous growth form, and a high probability of remaining vigorous, healthy and doniinant over undesired competing vegetation; (8) Strearnbanks have less than 5% exposed soils with margins anchored by deeply rooted vegetation or coarse-grained alluvial debris. 11. Projccts employing sumps or dry wclls for groundwater dischargc must conform to OAR 340- 044-050. Contact Barbara Priest, DEQ, at 503-229-5945 for more information. 12. DEQ reserves the option to modify, amend, or revoke tins 401 WQC for any or all activities or categories of activities, in the event that: a. New information indicates that the certified activities are having a significant adverse impact on State water quality or aquatic resources; b. State water quality standards, criteria, or beneficial uses are amended through rulemaking; or c. A proposed activity is necessitated by natural or human caused events which rcsult in sudden structural damage threatening human health and safety and determined by the_.

(2) Build the flow-redirection structure primarily of wood or otherwise incorporate large wood at a suitable elevation in an exposed portion of the structure or the bank key. Placing the large woody debris near strcarnbanks in the depositional area between flow direction structures to satisfy this requirement is not approved, unless thosc areas are likely to be greater than three feet in depth, sufficient for target-species rearing habitats. _ (3) Fill the trench excavated fOT the bank key above bankfull elevation with soil and topped with native vegetation. (4) The maximwn flow-redirection structure length wil! not exceed one- fourth of the bankfull channel width. (5) Place rock individually without end dumping, unless approvcd in writing by the appropriate Regulatory Authorities. (6) If two or more flow-redirection structures are built in a series, place the flow-redirection structure farthest upstream with 150 feet or 2.5 bankfull channel widths, from the flow-rediredion strudure farthest downstream. (7) Include wood riparian planting as a project component. Use of Laree Wood and Rock-Whenever possible"usc large wood as an integral component of streambank protection treatments. A"oid or minimize the use of rock, stone, and similar materials. i. - Large wood will be intact, hard, and undecayed to partly decaying with untrimmed rootwads to provide functional refugia habitat for fish. Use of decayed or fragmented wood found lying on the ground or partially sunken in the ground is not acceptable. 11. Rock may be used instcad of wood for the following purposes and structures. The rock may not impair natural stream flows into or out of secondary channels or riparian wetlands. Whenever feasible, place topsoil over the rock and plant with woody vegetation. (I) As ballast to anchor or stabilize largewoody debris components of an approved bank treatment. (2) To fill scour holes, as necessary to protect the integrity ofthe project, if the rock is limited to the depth ofthe'scour hole and does not extend above the channel bed. (3) To construct a footing, facing, head wall, or other protection necessary to _ prevent scouring or downcutting of. or slope erosion or failure <It, an __, existing structure (e.g., culvert, utility line, roadway or bridge support) to be repaired. (4) To construct a flow-redirection structure as described abovc. (5) In projects maintaining existing transportation related stmctures when an' ODOT or other registered professional engineer identifies rock alone as the only effective method due to site specific geotechnical or hydraulic concerns. -" :1 :1 I' II I II Section 401 Water Quality Certification for the RGP covering Nationwide catego~ies suspended by implementation of SPGP.

It is anticipated that stormwater plans for Tier 2A and Tier 3A projects will entail a short narrative paragraph and a rudimentary drawing which include the following elcments or justification for those elements which may not be applicable: (1) A site sketch or plan view drawing indicating the drainage flow directions and discharge locations, contours or spot elevations (preferably both) showing direction of stream and surface flow and location and oize of pro po oed facilities (e.g., parking lots, driveways, buildings, or roads) and nearest doWnstream waterbody, other physical features of the site, and the location and type of construction and post- construction BMPs; (2) Bl\1Ps- a. A description of proposed BMPs and a summary of their anticipated operation to ensure adequate capacity, proper function, and appropriate design for the sile such that qlllilily, quantity, and seasonality of pre-construction hydrologic conditions are mimicked to the maximwn extent practicable, based on stonnwater anticipated to be generated due to project- related impervious surfaces and delivered to waters o[the State. See local jurisdiction regulations and accepted stormwater manuals for detention and capacity requirements; b. A BMP implementation schedule, operation, and maintenance plan, and.designation of a party or agency with documentation of their agreement for responsibility for post-construction BMP maintenance; and c. A plan [or removal, recycling, and disposal of temporary BMPs which are not intended for post-construction use; or in lieu of (2) a, b, and c; d. Reference to implementation of a programmatic process developed to achieve these expectations, and acknowledged by DEQ as adequately addressing pollution control or reduction through basin-wide post-con~tnlction storrnwater managemenL. practices.
