Construction General Permit

QSD and QSP

Interested in becoming a QSD and QSP? Here is what you should know before you begin:

  • The Construction General Permit requires an underlying certification or registration as a prerequisite to becoming a QSP or QSD. A chart of acceptable certifications can be found on the State Water Board's website. You can take the QSP and QSD exams prior to obtaining the underlying certification, but you will not be awarded a QSP or QSD certificate until you have the underlying certification.
  • You must attend an in-person training before you register for an exam.
  • The registration fee for exams is $125. This covers both the QSP and the QSD exam.
  • If you fail the QSP exam, no certificates will be awarded.
  • If you pass the QSP exam but fail the QSD exam, you will be awarded a QSP certificate.
  • If you fail one exam, you are allowed one retake for a $67 fee. If you need to retake both exams, you only pay one $67 fee.
  • If you fail an exam twice, you will need to attend another in-person training before you are eligible to re-register for exams. The re-registration fee is $125.
