Limit maximum surface area of earth material exposed at any time to 245

300,000 square feet. Do not expose or disturb surface area of earth material 246

(including clearing and grubbing) until BMP measures are installed and 247 accepted in writing by the Engineer. Protect temporarily or permanently 248 disturbed soil surface from rainfall impact, runoff and wind before end of the 249 work day. 250

Immediately initiate stabilizing exposed soil areas upon completion of 252 earth disturbing activities for areas permanently or temporarily ceased on any 253 portion of the site. Earth-disturbing activities have permanently ceased when 254 clearing and excavation within any area of the construction site that will not 255 include permanent structures has been completed. Earth-disturbing 256 activities have temporarily ceased when clearing, grading, and excavation 257 within any area of the site that will not include permanent structures will not 258 resume for a period of 14 or more calendar days, but such activities will 259 resume in the future. The term “immediately” is used in this section to define 260 the deadline for initiating stabilization measures. “Immediately” means as 261 soon as practicable, but no later than the end of the next work day, following 262 the day when the earth-disturbing activities have temporarily or permanently 263 ceased. 264

For projects without an NPDES Permit for Construction activities, 278 complete initial stabilization within 14 calendar days after the temporary or 279 permanent cessation of earth-disturbing activities. 280

Any of the following types of activities constitutes initiation of 282 stabilization: 283

(1) Prepping the soil for vegetative or non-vegetative stabilization; 285

(2) Applying mulch or other non-vegetative product to the exposed 287 area; 288

(3) Seeding or planting the exposed area; 290

(4) Starting any of the activities in items (1) – (3) above on a portion 292 of the area to be stabilized, but not on the entire area; and 293

(5) Finalizing arrangements to have stabilization product fully 295 installed in compliance with the deadline for completing initial 296 stabilization activities. 297

Any of the following types of activities constitutes completion of initial 299 stabilization activities: 300

(1) For vegetative stabilization, all activities necessary to initially 302 seed or plant the area to be stabilized; and/or 303

(2) For non-vegetative stabilization, the installation or application 305 of all such non-vegetative measures. 306

If the Contractor is unable to meet the deadlines above due to 308 circumstances beyond the Contractor’s control, and the Contractor is using 309 vegetative cover for temporary or permanent stabilization, the Contractor 310 may comply with the following stabilization deadlines instead as agreed to by 311 the Engineer: 312

Engineer. 327

Follow the applicable requirements of the specifications and special 329 provisions including Section 619 Planting and Section 641 Hydro-Mulch 330

Seeding. 331

The Contractor’s designated representative specified in Subsection 442

209.03(A)(2)(d) shall address any Site-Specific BMP deficiencies brought up 443 by the Engineer immediately, including weekends and holidays, and 444 complete work to fix the deficiencies by the close of the next work day if the 445 problem does not require significant repair or replacement, or if the problem 446 can be corrected through routine maintenance. Address any Site-Specific 447

BMP deficiencies brought up by the State’s Third-Party Inspector in the 448 timeframe above or as specified in the Consent Decree or MS4 NPDES 449

209-11a 5/20/2026

Permit, whichever is more stringent. The Consent Decree timeframe 450 requirement applies statewide. The MS4 NPDES Permit only applies to 451

Oahu. In this section, “immediately” means the Contractor shall take all 452 reasonable measures to minimize or prevent discharge of pollutants until a 453 permanent solution is installed and made operational. If a problem is 454 identified at a time in the day in which it is too late to initiate repair, initiation 455 of repair shall begin on the following work day.

Site-Specific BMP deficiencies, the Engineer reserves the right to employ 464 outside assistance or use the Engineer’s own labor forces to provide 465 necessary corrective measures. The Engineer will charge the Contractor 466 such incurred costs plus any associated project engineering costs. The 467

Engineer will make appropriate deductions from the Contractor’s monthly 468 progress estimate. Failure to apply Site-Specific BMP measures may result 469 in one or more of the following: assessment of liquidated damages, 470 suspension, or cancellation of Contract with the Contractor being fully 471 responsible for all additional costs incurred by the State. 472

(C) Discharges of Storm Water Associated with Construction 474

Activities. If work includes disturbance of one acre or more, an NPDES 475

Permit authorizing Discharges of Storm Water Associated with Construction 476

Activity (CWB-NOI Form C) or Individual Permit authorizing storm water 477 discharges associated with construction activity is required from the 478

Department of Health Clean Water Branch (DOH-CWB). 479
