(A) Erosion, sediment, and temporary stormwater control measures.
(1) On-site sediment control measures shall be constructed and functional prior to initiating clearing, grading, stripping, excavating, or fill activities on the site.
(2) Sediment control measures and temporary stormwater control measures are to be maintained so they are operating effectively until permanent ground surface protection and permanent stormwater control measures are established in a manner specified in the applicable permit issued pursuant to this chapter.
(3) Fully functioning temporary sediment control measures (including, but not limited to, perimeter sediment controls) shall remain in place until the ground is stabilized with permanent ground cover. The intent of the chapter is to keep the sites protected at all times until the ground is permanently stabilized. In cases where it is not practical to leave the temporary sediment control measures in place prior to establishing permanent ground cover (for example when control measures need to be removed in order to grade the area or install pavement or sod) an exception will be made only if one of the conditions listed below will be met. In no way does adhering to one of the conditions below relieve the owner of responsibility to clean-up or repair any damages caused from sediment or stormwater runoff leaving the site.
(a) Permanent ground cover shall be established with pavement, aggregate, or sod within three days of the removal of sediment barriers.
(b) Permanent vegetation shall be established by seeding with anchored mulch within three days of removal of sediment barriers during the spring or fall seeding periods. However, on project areas with slopes not exceeding 5%, permanent vegetation shall be established by seeding within three days of the removal of sediment barriers during the spring of fall seeding periods. Summer seeding is acceptable on project areas which shall be watered. This does not apply to concentrated flow areas.
(B) Additional control measures. The Erosion Control Administrator may require additional control measures pursuant to the standards if determined as necessary after site inspection, and prior to issuing the permit.
