CGP Basics

When You Need a CGP

Figuring out whether your construction project needs a Construction General Permit (CGP) is an important first step. Generally, a CGP is required if your project involves disturbing a large area of land. Even smaller projects within a larger development might need one if the total disturbed area across the development surpasses certain thresholds.

Knowing these permit requirements is key to ensuring your project complies with Maryland’s specific regulations.

Maryland CGP Rules

In Maryland, managing stormwater effectively is a must. This often means implementing drainage solutions designed to control runoff and prevent erosion. Pro Landscapes MD specializes in providing these solutions, including French drains, berms and swales, box and pipe drain systems, regrading, sump pump installation, and leveling and grading – all tailored to meet local standards.

Required Documents

Preparing the right documentation is key to successfully applying for a CGP in Maryland. The Maryland Department of the Environment (MDE) requires applicants to submit several important documents, each needing careful attention to detail.

Notice of Intent Form

The Notice of Intent (NOI) form is the centerpiece of your CGP application. This form must include:

• The project’s location with exact coordinates
• The operator’s legal name and contact details
• Documentation showing authority to operate
• Names and locations of any affected water bodies
• Total disturbed area, measured in acres
• The project timeline, including start and completion dates ^[1]

Site Maps

Your site maps, drawn to scale (commonly 1" = 50′ or 1" = 100′), should provide a clear visual representation of the project. These maps must include:

These maps work in tandem with your erosion control plans, ensuring all compliance requirements are met ^[2].

Erosion Control Plans

Erosion control plans must outline both immediate and long-term strategies for stabilizing soil, following Maryland’s 2011 Standards and Specifications. Be sure to include:

Short-term Controls:

• Temporary seeding with annual rye grass
• Mulching (2-3 inches of straw)
• Erosion control blankets for slopes steeper than 3:1
• Sediment trap sizing calculations
• Perimeter control measures like silt fences

Long-term Solutions:

• Plans for establishing permanent vegetation
• Soil amendment details based on testing results
• Stormwater management structures
• Maintenance schedules for all permanent controls ^[2]

All submitted documents must align with Maryland’s General Permit for Stormwater Discharge Associated with Construction Activity (20-CP), which went into effect on April 1, 2023 ^[2].

Stormwater Prevention Plan

Once the necessary documents are in place, the next step is creating a solid Stormwater Pollution Prevention Plan (SWPPP). This plan is crucial for managing stormwater during construction and is a key requirement for your CGP application. It outlines strategies to prevent pollution and ensure proper drainage throughout the site.

Erosion Controls

To minimize erosion, focus on solutions that work with the natural flow of water on your site. Features like berms and swales can help redirect water away from vulnerable areas, reducing the risk of erosion. For sites expecting large volumes of stormwater, consider adding box or pipe systems to improve water management and maintain site stability.

Site Inspections

Set up a regular inspection schedule to ensure all stormwater controls are functioning as intended. These routine checks help catch potential problems early and allow for quick fixes. Keep thorough records of inspections to stay compliant with regulations.

Spill Response

Create a spill response plan that outlines how to prevent and handle accidental releases of chemicals or fuel. Train your team on these procedures so they’re prepared to act quickly if needed. Update the plan regularly to reflect any changes in site operations or conditions.

Filing and Follow-up

How to Submit

To file your CGP application, use Maryland’s ePermits portal. Before submitting, double-check that your Notice of Intent (NOI) and Stormwater Pollution Prevention Plan (SWPPP) are accurate and complete. Ensure all required signatures are included, and upload supporting documents in PDF format. It’s a good idea to save digital copies of everything you submit, including confirmation numbers and timestamps. Once filed, you’ll receive a unique tracking ID that you can use for future updates or modifications to your application.

After submission, organize your records to make ongoing compliance easier to manage.

Required Records

Keep detailed records to stay compliant. The key documents include:

• Inspection Reports: Record site conditions every seven days or within 24 hours of a rainfall event measuring 0.25 inches or more.
• Maintenance Records: Log all repairs and updates to erosion and sediment control measures.
• Training Documentation: Maintain proof of staff training on SWPPP procedures.
• Corrective Action Reports: Document any violations and the corrective steps taken to resolve them.

Store these records in both digital and physical formats. Digital files should be backed up regularly and accessible to essential team members. Physical copies should be stored on-site in a weatherproof location to ensure they remain intact.

Closing the Permit

When your project reaches final stabilization – meaning at least 70% perennial cover is established on unpaved areas – you can begin the process to close your permit.

Steps to close the permit include:

1. Document Site Conditions: Take clear, dated photographs showing all stabilized areas.
2. Complete a Final Inspection: Verify that all temporary erosion and sediment controls have been removed.
3. Submit the Notice of Termination (NOT) Form: File this form through the ePermits portal.

Be sure to keep all permit-related records – such as inspection reports, maintenance logs, and any correspondence with regulatory agencies – for at least three years after submitting your Notice of Termination. This helps ensure you’re prepared for any future audits or inquiries.

Conclusion

Securing a CGP requires careful attention to documentation and effective stormwater management. Proper drainage planning and adherence to regulations are not just critical for obtaining the permit – they’re key to maintaining the site’s stability over time.

To wrap up the process, all compliance measures must come together seamlessly. A successful CGP application incorporates well-thought-out drainage systems, grading plans, and erosion control strategies. These elements are essential for both meeting permit requirements and ensuring the site remains stable in the long run.

Key compliance practices include:

• Keeping detailed records of inspections and maintenance activities
• Implementing erosion control measures effectively
• Ensuring consistent and accurate documentation

What steps can I take to ensure my construction project complies with Maryland’s CGP regulations?

How to Stay Compliant with Maryland’s Construction General Permit (CGP)

If you’re managing a construction project in Maryland, staying compliant with the Construction General Permit (CGP) regulations is a must. To help you navigate this process, here’s a straightforward guide to keep your project on track:

• Submit Essential Paperwork: Before breaking ground, file a Notice of Intent (NOI) and prepare a Stormwater Pollution Prevention Plan (SWPPP). Double-check that all documents are complete and current.
• Use Effective Erosion Controls: Implement erosion and sediment control measures like silt fences, sediment basins, and stabilized entrances to reduce environmental impact and prevent runoff issues.
• Inspect the Site Regularly: Schedule frequent site inspections to ensure your project aligns with the SWPPP. Address any problems quickly to avoid compliance setbacks.
• Keep Detailed Records: Maintain thorough documentation of inspections, maintenance activities, and any updates to the SWPPP. These records are essential if your project is audited.

Staying organized and proactive makes compliance much easier. If you’re unsure about any requirements, reaching out to professionals with expertise in CGP regulations can save you time and effort.

What should I do if changes to my project size impact the initial fee or annual maintenance costs for the CGP?

If your project grows or shrinks in size, impacting the original fee or yearly maintenance costs for the CGP, you need to update your application without delay. Reach out to the appropriate permitting authority to inform them of the changes and submit any extra paperwork they request. The updated project scope might lead to changes in fees or requirements.

Taking care of these updates promptly helps you sidestep potential delays or issues in the permitting process while staying fully compliant with regulations.
