Maryland is the home market for International Cover Systems. ICS is headquartered in Middle River, Baltimore County — and Maryland project sites benefit from the shortest mobilization times, the deepest accumulated project experience in the state, and the most direct relationship with MDE staff, environmental consultants, and general contractors who work in the region. From Chesapeake Bay Critical Area containment projects on the Eastern Shore and tidewater areas to NPDES MS4 stormwater infrastructure in the Baltimore-Washington corridor, ICS brings comprehensive geomembrane liner installation capability to Maryland projects of every scale and complexity.
Chesapeake Bay Critical Area Compliance and Tidewater Containment
Maryland’s Chesapeake Bay Critical Area Act imposes strict development and containment requirements on properties within 1,000 feet of tidal waters — a regulatory zone that covers a substantial portion of the Chesapeake Bay shoreline in Anne Arundel, Queen Anne’s, Talbot, Dorchester, Somerset, Wicomico, and Worcester Counties, as well as Baltimore City waterfront areas. Containment projects within the Critical Area require coordination with MDE and the local Critical Area Commission, and liner systems must meet engineering standards that demonstrate no net increase in nutrient or sediment loading to tidal waters. ICS understands the Critical Area regulatory framework and brings this compliance knowledge to liner system design and installation for waterfront industrial, agricultural, and stormwater management projects across tidewater Maryland.
The Eastern Shore’s role as one of the highest-density poultry production regions in the United States — with Perdue, Tyson, and Mountaire operations concentrated in Wicomico, Dorchester, and Worcester Counties — drives significant demand for poultry house waste storage liner systems and agricultural lagoon liner installation and replacement. MDE’s Water Management Administration regulates agricultural waste storage under Maryland’s Nutrient Management Law, and properly lined manure storage structures are a compliance requirement for operations near Chesapeake Bay tributaries. ICS installs agricultural containment liner systems for Eastern Shore poultry and agricultural operations with the field efficiency and documentation practices that MDE compliance requires.
Baltimore-Washington Corridor Industrial and Municipal Liner Projects
The Baltimore metropolitan area and DC suburbs generate consistent demand for secondary containment, stormwater management, and industrial liner projects. MDE NPDES MS4 stormwater permit compliance drives capital investment in stormwater retention basins and bioretention liner systems across Baltimore County, Howard County, Montgomery County, and Prince George’s County. Major wastewater infrastructure — including Blue Plains Advanced Wastewater Treatment Plant in DC (a regional facility serving Maryland jurisdictions) and Back River and Patapsco River wastewater treatment plants in Baltimore — involves large-scale liner systems in treatment basins and equalization structures. Secondary containment for the Port of Baltimore’s fuel terminals, chemical distribution facilities, and cargo handling areas is a consistent project type for ICS given the port’s proximity to ICS headquarters.

Areas Served in Maryland
ICS serves project sites throughout Maryland with particularly strong coverage of the Baltimore metro area (Baltimore City, Baltimore County, Harford County, Anne Arundel County, Howard County), the Eastern Shore (Wicomico, Dorchester, Worcester, Somerset, Talbot, Queen Anne’s, Kent, and Caroline Counties), the DC suburbs (Montgomery and Prince George’s Counties), and Western Maryland (Frederick, Washington, Allegany, and Garrett Counties).
Frequently Asked Questions — Maryland Geomembrane Liner Installation
Why is ICS particularly well-positioned to serve Maryland liner projects?
ICS is headquartered in Middle River, Baltimore County — Maryland is our primary home market. This means the fastest mobilization times, the deepest familiarity with MDE regulatory requirements and local environmental consultant relationships, and accumulated project experience across the state’s diverse project types — from tidewater agricultural containment on the Eastern Shore to industrial secondary containment in the Baltimore port area. For Maryland project owners and general contractors, ICS offers the responsiveness and local knowledge of a regional contractor backed by multi-state geomembrane installation expertise.
How does Maryland’s Chesapeake Bay Critical Area Act affect liner installation projects near tidal water?
The Critical Area Act requires MDE review and local Critical Area Commission approval for development activities — including construction of containment structures — within 1,000 feet of tidal waters in Maryland. Containment projects must demonstrate compliance with Critical Area standards, including limitations on impervious surface and requirements for nutrient and stormwater management. Liner systems within the Critical Area must be engineered to prevent any increase in nutrient loading to adjacent tidal waters. ICS works with project engineers and environmental consultants on containment system designs that satisfy Critical Area requirements.
Does ICS install agricultural lagoon liner systems for Eastern Shore poultry operations?
Yes. Agricultural lagoon liner installation and replacement for poultry waste storage is a well-established project type for ICS on the Eastern Shore. Liner systems for poultry waste storage must meet MDE Nutrient Management Program requirements and are typically installed in coordination with the farm’s nutrient management consultant. ICS installs HDPE and RPP liner systems appropriate for agricultural waste storage applications and provides material documentation for MDE compliance files.
What liner materials does ICS recommend for stormwater management basins in the Baltimore-Washington corridor?
HDPE is the most commonly specified geomembrane for permanent stormwater management basins due to its UV resistance, chemical inertness, and long service life. LLDPE is preferred for basins with complex geometry where HDPE’s stiffness creates installation challenges. For temporary erosion and sediment control basins, RPP or Dura-Skrim materials may be appropriate. Material selection is coordinated with the civil engineer of record and reflects the basin’s design hydraulic head, geometry, and maintenance access requirements.
How quickly can ICS mobilize to a Maryland project site?
For Maryland projects, ICS typically offers the fastest mobilization timelines of any state we serve. From our Middle River headquarters, ICS can reach most Maryland project sites within a few hours. For urgent remediation or emergency containment projects, ICS can assess mobilization within days depending on material availability.
