9 HAZARDOUS MATERIALS
10 ENVIRONMENTAL
10.1 Environmental Clearance Type and
Date:
10.2 Environmental Commitments:
10.3 Waterway Permits:
It
is required that the bidder be aware of need for Section 404/401: Permits/Certifications for all projects
impacting "waters of the US".
The level of permit, that is Nationwide versus Individual 404 and 401,
is determined by the exact amount of impact to "waters of the US",
(i.e., acreage of fill activities in a stream or wetland or linear feet of work in a
stream) and in some cases the waters impacted.
All individual 404 Permits require 401 Water Quality Certification. Nationwide Permits are activity specific
permits used to authorize projects with minor impacts. Projects with more than minor impacts
require individual review by the U.S. Army Corps of Engineers and the Ohio
Environmental Protection Agency.
The DBT should be aware of the
Nationwide Permits and conditions as issued for the State of Ohio and should
design projects to meet the requirements of these general permits to avoid the
requirements for Individual 404/401 Permits if possible. The Nationwide Permits for the State of Ohio
can be found of the various Corps of Engineers’ web sites. The Huntington District’s web site can be
found at: http://www.lrh.usace.mil/or/permits/.
Coordination of the waterway
permits can take up to six (6) months for Individual 404 Permits. Therefore it is imperative that the DBT
perform the design and construction work according to the limitations and
guidelines of the permits as specified below.
The DBT shall submit plans (i.e., plan & profile, cross-section and
detail sheets for any bridges, culverts, or fill areas in waters) to the County
Engineer, for permit conformance determination, no less than 90 days prior to
any in stream or wetland work. The
review of plans, any required coordination or the processing of permit
applications must be accomplished by the County Engineer prior to the
commencement of construction
activities. At no time will the DBT
coordinate waterway permit issues directly with the permitting agencies unless
directed to do so by the County Engineer.
The environmental waterway permits
governing the subject improvement are as follows:
10.4 National Pollutant Discharge Elimination System (NPDES) permit : The Storm Water Pollution Prevention Plan (SWPPP) must be submitted by the DBT to the County Engineer for approval prior to any earth moving activities. The DBT must also apply for a NPDES permit. This requires filing a Notice of Intent for coverage in accordance with Ohio EPA’s procedures. The NOI shall be filed by the Project Manager. (For information about OEPA’s NPDES permit requirements see: http://www.epa.state.oh.us/dsw/storm.html.) This EPA permit shall be approved prior to any earth disturbing activities.
10.5 Temporary and Permanent Erosion
Control : All other requirements relating to temporary and permanent
erosion and water pollution controls shall be in accordance with section 107.21
of the Construction and Material Specifications and Supplemental Specification 877 including section 877.05 as
modified in the design-build proposal.
All
temporary erosion control items shall be removed before the project is
accepted. Removed materials shall
become the property of the DBT and shall be disposed of in accordance with Item
203.
10.6 Stream Crossing Investigations ( flood plain analysis) : The DBT team shall perform a detailed flood plain analysis for each waterway crossing. The analysis shall be as per the Location & Design Manual and The Bridge Design Manual and as follows : The extent of the analysis shall be from a minimum of 500' downstream, to the greater of either one bridge opening/width upstream, or to the limits of the area inundated by the 100-year event. The results of the detailed flood plain study, supporting hydraulic calculations, and recommendations shall be submitted to the County Engineer for review and comment prior to construction of the drainage structure. If the proposed crossing is located in a special flood hazard area as defined by FEMA, the detailed flood plain analysis shall be submitted concurrently to the local flood plain coordinator.
11 RIGHT OF WAY (ROW)
All necessary construction work for the project will be performed within the existing right of way.
Existing right of way lines will be located by the DBT based on requirements specified in Chapter 4733-37 of the Ohio Revised Administrative Code (Board Rules) governed by regulations outlined in Chapter 4733, Ohio Revised Code (Regulation Laws). It is the responsibility of the DBT to research existing right of way information from all available sources including but not limited to ODOT records, County road records, Commissioners’ Journals and records of other County offices to the extent necessary to provide an accurate basis for the establishment of the existing right of way.
The DBT will stake and flag the existing right of way in the field prior to the start of construction and will maintain said stakes and flags throughout the duration of the project.
The DBT will identify and show all right of way encroachments on the construction plans at the Conceptual Review Submission. The County Engineer will be responsible for clearing all encroachments on Federal-aid projects in accordance with standard encroachment removal.

19 BUILDABLE UNITS (BU)
Definition : Buildable Units are portions of the projects which can be designed, reviewed and built with only limited controls and assumptions coming from the design of other portions of the project. Often a Buildable Unit will be defined by a geographic area within the plan, but it may also be defined by types of work or construction stages which may require or permit similar, nearby work to be divided into separate Buildable Units. All Buildable Units shall summarize the materials required to construct that portion of the project. The summary shall include the Construction and Material Specifications Item Number, and a description of the materials to be used.
General : After the approval of the Preliminary Plan, The DBT may break the project work into two or more separate BU which can be progressed through design and construction with minimal or known effect on each other and/or which can be dealt with sequentially such that sufficient data is available for design and review of each BU. In order that the design and construction of one BU may proceed without significant approved information from an associated BU, the DBT may develop and propose assumptions which will allow for the first BU to proceed through design and/or construction. These assumptions shall be submitted for review and comment but their accuracy and effort upon the final design are the sole responsibility of the DBT. Should error in these assumptions result in additional work, remedial work or other changes to assure an acceptable design or should they result in the need to remove work and substitute additional work, the DBT shall be responsible for all such costs including, removal of unacceptable materials from the site, modification, additional work, repairs, etc. as necessary to produce an acceptable result.
If the DBT elects to develop Buildable Units, the DBT shall prepare, for review by the County Engineer, a table of Buildable Units for the project with each BU described in detail. If the table is approved, the DBT shall modify the Progress Schedule to show a separate group of activities for BU and these activities shall encompass all of the design and construction work in each BU. Work activities shall be further separated in the Progress Schedule to show a meaningful completion status (i.e. separate activities comprising the placement of a bridge deck on steel beams shall describe; shoring, form building, steel placement, placement of conduit & joints, pouring concrete, forming parapets, pouring or slip forming parapets, provision of membranes, provision of wearing surfaces, curing, repair, form removal, cleaning, etc.)
The
Final Review Submission and construction plans shall specifically be identified
by the Buildable Unit code. If the
design of a BU requires input information from an adjacent or related BU, the
source for that information in previously approved plans shall be cited or the
DBT shall provide an estimated value of the data. The input data shall also be carefully identified. In the same way any assumption, calculations
or results from the stage and BU which are used as input to another BU shall be
similarly identified, and where appropriate, compared back to that BU to verify
previous assumptions. Should
assumptions not match values calculated later, the DBT shall re-analyze all
affected components and determine appropriate changes. Should those elements have already been constructed,
the DBT shall recommend repairs, adjustments, modifications or replacement of
the existing work as necessary to comply with the Scope of Work. All costs for re-design, re-submissions,
modifications, removals, disposal of materials and new work needed to remedy
the project and bring it to compliance shall be borne by the DBT and no time
extensions shall be approved for this.
