What the CPP is and how it works

According to South Coast Air Quality Management District, “These courses are not prerequisites for taking the CPP examination. Anyone with sufficient background and expertise in permit application completion and filing is welcome to take the CPP examination.”^[2]

The CPP is a certification from the South Coast Air Quality Management District. People who pass earn the title "Certified Permitting Professional" and may keep the CPP license by renewing it each year.

The exam is given in person at South Coast AQMD headquarters in Diamond Bar, CA. It is open-book and open-notes. You need to bring your own calculator, and you may use a computer for viewing files only. The district normally holds the exam once a year, so check the official announcement for the current date before you plan around it.

Eligibility is open. There is no prerequisite course, and anyone with sufficient background and expertise in permit application completion and filing is welcome to sit the exam.

The exam fee is $224.52, and it also covers the first-year license fee for those who pass. The license renews at $224.52 per year. Under District rules, a license expires if the renewal fee is not received, postmarked or electronically paid within 30 days after invoices are sent.

Worked examples: how to reason through CPP questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: What is a 'wetland delineation' and who is qualified to perform one in the US?

1. A field investigation identifying wetland boundaries using hydrology, hydric soils, and hydrophytic vegetation criteria
2. A review of FEMA flood maps to identify wetland areas
3. An aerial photograph analysis of potential wetland areas
4. A state agency determination based on parcel zoning records

Answer: A. A field investigation identifying wetland boundaries using hydrology, hydric soils, and hydrophytic vegetation criteria

Explanation:

The correct answer is the field investigation. A wetland delineation maps where a wetland begins and ends on the ground, using three tests: hydrology, hydric soils and hydrophytic vegetation. Qualified environmental scientists or engineers carry it out.

A review of FEMA flood maps shows flood risk, not wetland conditions. An aerial photograph analysis can flag areas worth checking, but it does not confirm a boundary. A state determination based on parcel zoning records looks at how land is classified on paper, not at water, soil or plants.

Rule to remember: a delineation is a field finding based on physical evidence, and desk reviews only point to where fieldwork is needed.

Example 2

Question: Which technique is most effective for reaching underrepresented communities during public participation in permitting?

1. Targeted outreach through community organizations and translated materials
2. Publishing notice only in the Federal Register
3. Holding hearings exclusively during business hours at agency offices
4. Relying solely on project applicant outreach

Answer: A. Targeted outreach through community organizations and translated materials

Explanation:

The correct answer is targeted outreach through community organizations and translated materials. It reaches people where they already are, in a language they read, through groups they trust.

Publishing notice only in the Federal Register reaches few residents, since most people never read it. Holding hearings only during business hours at agency offices excludes people who cannot leave work or travel there. Relying solely on the applicant's outreach leaves the engagement to the party with a stake in the outcome, and it may not reach affected neighbours at all.

Rule to remember: effective participation removes barriers of time, place and language, and does not rest on a single formal notice.

Example 3

Question: What document is typically required for environmental approval?

1. Environmental Impact Assessment (EIA)
2. Financial forecasting documents.
3. Project marketing plans.
4. Supplier contracts.

Answer: A. Environmental Impact Assessment (EIA)

Explanation:

The correct answer is the Environmental Impact Assessment (EIA). It is a study of the likely environmental effects of a proposed project, and decision-makers use it to understand and reduce adverse impacts before granting environmental clearance.

Financial forecasting documents describe expected costs and revenue, which matter to the sponsor but do not address environmental effects. Project marketing plans describe how a project will be promoted. Supplier contracts set out purchasing terms. None of these evaluates environmental consequences, so none supports an environmental approval.

Rule to remember: match the document to the question being asked. Environmental approval calls for an environmental study.

How to use these practice tests

Start with the official material. Read the CPP manual and the exam announcement from South Coast AQMD so you know how the exam is run and what is expected of a permitting professional. Because the exam is open-book, your aim is to know where to find answers quickly, not to memorise everything.

Then work through our practice sets one topic at a time. Begin with the area where your daily work gives you the least exposure, such as Environmental Impact Assessment or Legal Authority and Jurisdictional Issues. After each set, read the explanation for every question you missed and write down the rule behind it.

Next, cover the process topics: Application and Documentation Processes, Permitting Regulations and Compliance and Project Planning and Coordination.

In the last stretch, retake the sets you found hardest and build an indexed set of notes you can search quickly on exam day. Bring your calculator and check the official announcement for the date and location. Remember that our questions are written by us and are not real exam questions.
