210-3.01 General

a. In the event of conflict between these specification requirements and any pollution control laws, rules or regulations of other Federal, Commonwealth or local agencies, the more restrictive laws, rules or regulations shall apply.

b. At the pre-construction conference, prior to the start of construction work, the

Contractor shall submit to the Engineer for review and approval his proposed plan and schedule for the temporary and permanent erosion control work. The schedule shall detail the proposed coordination for accomplishing the temporary and permanent erosion control work in a timely and appropriate manner. No construction work shall be started until the schedule has been approved and the necessary controls installed as required for the particular operation to be in progress.

c. The Contractor shall incorporate all permanent erosion control features into the project at the earliest practical time in order to minimize the need for temporary erosion control measures and this should be reflected in his proposed schedule.

d. If the Engineer determines that the Contractor is not in compliance with the approved erosion control schedule, or field conditions warrant changes in the plan, the Contractor shall submit a revised schedule for performing erosion control work and no work contingent upon the revised schedule shall be continued or started until the revised plan has been approved.

e. Clearing and grubbing operations shall be so scheduled and performed that grading operations and permanent erosion control features can follow immediately thereafter if the project conditions permit; otherwise, temporary erosion control measures may be required between successive construction stages. Under no conditions shall the surface of the erodible earth material exposed at one time by clearing and grubbing exceed 70,000 square meters unless such areas are protected by adequate temporary erosion control measures approved by the

Engineer.

f. Excavation, borrow, and embankment operations shall also be scheduled and performed to permit permanent erosion control features to follow immediately thereafter if project conditions permit; otherwise, temporary erosion control measures may be required.

Under no conditions shall the surface area of erodible earth material exposed at one time by excavation, borrow, or fill exceed 70,000 square meters without the prior installation of adequate erosion control measures approved by the Engineer.

g. The Engineer has the authority to limit the surface area of erodible earth material exposed by clearing, grubbing, excavation, borrow and embankment construction operations in progress commensurate with the Contractor's capability and progress in keeping temporary erosion control measures and the finish grading, mulching, seeding and other such permanent erosion and pollution control measures current in accordance with the accepted schedule. The

Engineer has also the authority to increase or decrease the amount of surface area of erodible earth material to be exposed at any one time by clearing, grubbing, excavation, borrow and embankment construction operations as determined by his analysis and evaluation of existing project conditions.

h. The Engineer has the authority to direct the Contractor to immediately provide erosion control measures to prevent soil erosion that will adversely affect construction operations, SP-5
