(2) Any condition and/or requirements established by the Director to protect specific watersheds or drainage basins.

d. The owner of a new development or redevelopment project, the owner's successors and assigns, and each named responsible party, shall implement and adhere to the terms, conditions and requirements of the approved PCSMP. Each failure by the owner, the owner's successors or assigns, or a named responsible party, to implement and adhere to the terms, conditions and requirements shall constitute a violation of this Chapter.

e. The Director may require that the PCSMP maintenance agreement or covenant for maintenance of post-construction stormwater management control system be recorded with the County Recorder's Office by the owner. The signature of the owner, any successive owner or the named responsible party shall be sufficient for the plan or any revised plan and a signature on behalf of the County shall not be required for recordation.

g. The costs and expenses of the County incurred in the review, approval, or revision of a PCSMP or other Development requirements (or in the approval or revision of any such requirement) shall be charged to the owner, owner's agent or responsible party and shall be due and payable to the County. The Director may elect to require a deposit of estimated costs and expenses, and the actual costs and expenses shall be deducted from the deposit, and the balance, if any, refunded to the owner, owner's agent or responsible party.

h. Compliance with the conditions and requirements of a PCSMP shall not exempt any person from the requirement to comply independently with each provision of this Chapter.

The Director may adopt requirements identifying appropriate BMPs for any activity, operation, or facility which may cause or contribute to pollution or contamination of the County Storm Drain System, and every person undertaking such activity or operation, or owning or operating such facility, shall comply with such requirements.

Notwithstanding the presence or absence of requirements promulgated pursuant to the foregoing subsection a., any person engaged in activities or operations, or owning facilities or property, which will or may result in pollutants entering the County Storm Drain System, or any Receiving Waters, shall implement BMPs to the extent they are technologically and economically achievable to prevent and reduce such pollutants.
