U.S. FISH AND WILDLIFE SERVICE RESPONSE

DURING THE CHALK POINT OIL SPILL

Introduction

As a federal trustee for the nation’s wildlife resources, the U.S. Department of the Interior’s (DOI) Fish 

and Wildlife Service (FWS) has a responsibility to conserve, enhance, and protect fish and wildlife, their 

habitats, and refuge lands. This responsibility includes prevention of, and response to spills, both chemical 

and oil. Spill response is a significant role for FWS personnel to address when FWS trust resources are 

involved. Duties carried out by FWS personnel during a spill event include: documenting impacts to 

wildlife and their habitats, keeping wildlife out of impacted areas, collecting dead and injured wildlife, 

identifying sensitive environments, providing oversight of wildlife rehabilitation groups, and gathering 

information for potential Natural Resources Damage Assessment. This report focuses on the wildlife 

response activities conducted by FWS personnel during the Chalk Point oil spill which took place April 7, 

2000 near the town of Aquasco, Maryland. The spill, which resulted from a ruptured underground 

pipeline that transported oil to the Potomac Electric Power Company (PEPCO) Chalk Point Facility, 

released approximately 126,000 gallons of a mixture of #2 and #6 fuel oil into Swanson Creek, a tidal 

tributary of the Patuxent River. The main stem of the Patuxent River, associated shoreline habitats, and 

other tributaries were also impacted by oil after heavy winds on the evening of April 9 blew oil over 

containment booms placed at the confluence of Swanson Creek and Patuxent River. During the spill, as 

many as 18 technical staff from the FWS and DOI were involved in response, with over 2,700 man hours 

documented. Fortunately, the spill occurred at a time when most migratory fish and birds (waterfowl) had 

already passed through the Patuxent River area. Most anadromous fish returning from higher saline 

waters of the Bay to spawn in the upper reaches of the Patuxent had spawned weeks earlier. A majority 

of the waterfowl had already left the Patuxent River system for the Canadian breeding grounds some time 

in late March. Had the spill occurred a month or two earlier, wildlife impacts would probably have been 

much greater. During the spill, extensive wetland habitats were impacted as were a number of other FWS 

trust resources including migratory birds (mostly waterfowl). FWS response activities were broken 

down into 5 major categories: wildlife survey teams, wildlife rehabilitation, wildlife morgue operations, 

protection of threatened and endangered species, and identification of environmentally sensitive areas. 

The following is a summary of each activity.
2

Wildlife Survey Teams 

One of the first tasks of the FWS Field Response Coordinator (FRC) was to develop wildlife survey 

teams. The purpose of the teams was to document wildlife impacts and use within the spill zone. The 

wildlife survey teams were made up of 2-4 individuals that were composed of personnel from FWS, 

Maryland Department of Environment (MDE), Maryland Department of Natural Resources (MDNR), 

and, later, by trained volunteers. The initial number of teams was four and later expanded to 12 teams. 

Each team was radio equipped and assigned a specific shoreline zone within Swanson Creek or the 

Patuxent River. Within each zone each survey team recorded on spill data sheets the following 

information: wildlife observed within the zone (number and species); degree of oiling (none, lightly, 

moderately, or heavy) on observed wildlife; extent of oiling along shoreline (none, light, moderately, and 

heavy). In addition, each team collected any dead wildlife they encountered. Dead specimens were 

placed into plastic bags and labeled with date and location. In the event that oiled wildlife (still alive) were 

observed, teams were instructed to not attempt capture, but to radio the Wildlife Trailer located at the 

Command Center (PEPCO Chalk Point facility) with the following information: species, number, degree 

of oiling; landowner’s name , address, and phone number if available; and any visible landmarks. Upon 

receiving the information, the FWS dispatched a wildlife rehabilitation response team to attempt to 

capture the impacted wildlife. To facilitate a more rapid wildlife recovery effort, and reduce response 

time, a number of response boats were also used in the recovery effort. Captured animals were 

transported to the wildlife triage area (building No. 7 at PEPCO Chalk Point Facility) and treated 

appropriately before being transported to an off-site rehabilitation center (Chesapeake Wildlife sanctuary, 

Bowie, MD [CWS], or Tri-State Bird Rescue and Research [TSBRR], Newark, DE). After each team 

had completed a zone survey, team leaders radioed in their survey data to the Wildlife Trailer where it 

was recorded on maps. The wildlife survey data was then passed on by the FRC to the Planning Section 

Chief. Time permitting, upon completion of their initial survey, wildlife survey teams were assigned 

another zone for surveying. Wildlife survey teams performed these tasks daily for the first nine days of the 

spill. Additional information on bird populations in the area was provided via an aerial survey conducted

by the MDNR on April 12, 2000. The survey encompassed the Patuxent River from Eagle Harbor to the 

mouth of the river (Table 1).

Wildlife surveys ended the week of April 17, 2000 when it was determined that there was minimal 

additional recovery of dead and injured wildlife. Results of the wildlife survey teams showed that the most 

commonly observed animal group were birds (Figure 1). Greater than 300 were observed the first day of 

the surveys, 50% of which were observed to be oiled to some degree (Figure 2). During the wildife 

surveys it was observed that when mammals (mostly muskrats) were encountered they were generally 

always oiled to some degree, usually 100% of the time (Figure 2). The last day wildlife surveys were 

conducted, the number of birds observed declined dramatically from the first day (i.e., 80% decline); 

however, those birds observed still showed signs of oiling, with greater than 30% deemed to be oiled 

(Figure 2).

Wildlife Rehabilitation Operations

The wildlife rehabilitation responsibilities of the FWS were limited to oversight of the rehabilitation efforts 

and consolidating the data from each of the two wildlife rehabilitators. The rehabilitation data included: 

species, number collected, number rehabilitated, number died in rehabilitation, and number released. The 

preceding information was provided to the FWS on a daily basis. Each morning a daily report of 

rehabilitation activities was compiled by the FWS and forwarded to the various units within the 

Command Center e.g., Joint Information Center and Planning, and to MDNR. As mentioned previously, 

rehabilitation and recovery of the oiled wildlife was conducted by TSBRR and CWS. In an effort to 

minimize conflict between the two rehabilitators, it was determined by the FWS that all incoming wildlife 

would be assessed by TSBRR veterinarians as either critical or non-critical. All critical care wildlife were 

handled by CWS because of the close proximity of their rehabilitation center located in Bowie, Maryland. 

 Non-critical wildlife were transported out of state to the TSBRR facility in Newark, Delaware. 

Upon arrival at the triage building, TSBRR and CWS conducted the appropriate rehabilitation 

procedures, which included taking swabs of fur/feathers and feet for potential criminal evidence. The 

swabs were wrapped in an aluminum foil, placed in plastic storage bags, and then frozen. The swabs 

were stored in a locked freezer located in the triage building. On a daily basis, the FWS would take 

possession of the swabs and complete a chain of custody. Upon completion of chain of custody, the 

swabs were stored in a locked freezer located in the triage building. Chain of custody was completed 

when the swabs were given to FWS Special Agents. The Service was also responsible for recording the 

numbers of wildlife which were rehabilitated. Animals which died during rehabilitation were also recorded 

into the animal logs, and processed accordingly (See Morgue section)

During the spill, personnel associated with the spill cleanup and private citizens were able to contact the 

Command Center and report the location of oiled wildlife through a wildlife hotline that was established. 

Most incoming calls came directly to the Wildlife Trailer, if not, they were passed on to the trailer by the 

Operations Section. When a hotline call was received, personnel from the FWS, TSBRR and/or CWS 

were dispatched to retrieve the oiled wildlife and returned it to the wildlife triage building. The FWS, with 

assistance from MDNR, manned the Wildlife Hotline until incoming calls were minimal. The maximum 

number of Wildlife Hotline calls (16) were received on day 5 after the pipeline release. After day 8 of the 

pipeline release, incoming Wildlife Hotline calls started to decline gradually. By day 13, incoming calls 

were two or less, by days 14-18, calls were less than two a day. (Figure 3). On April 26 (day 18 after 

the pipeline release),TSBRR and CWS received calls directly and recovered injured wildlife.

Wildlife rehabilitation operations involved the live capture of 204 individuals, most of which were 

waterfowl (53%) and reptiles (33%), the remaining 14% were comprised of mammals, fish and 

invertebrates (Table 2). Eighty five percent of the captured wildlife were successfully released back into 

the wild. Of those animals that died in rehabilitation, ruddy ducks and muskrat appeared to be the two 

most vulnerable species (Table 2).

Morgue Operations

As mentioned earlier, wildlife survey teams collected any dead wildlife they encountered. Later in the 

response effort, oil spill cleanup crews, and shoreline cleanup assessment teams (SCAT) also collected 

dead wildlife. All retrieved wildlife carcasses, and wildlife that died during the rehabilitation were 

processed by FWS personnel. After being labeled appropriately by the field or rehabilitation teams, each 

carcass was placed in a plastic bag, and taken to the PEPCO wastewater laboratory for processing (i.e., 

“the morgue”). Prior to being processed, the carcasses were temporarily stored at the laboratory or 

triage building in a freezer/refrigerator. The appropriate information for each wildlife carcass was entered 

into an animal logbook located in the laboratory. The logbook entries included an identification number, 

species, location of collection, time of retrieval, and general observations. An identical logbook was kept 

at the Wildlife Trailer. When the wildlife carcasses were being prepared for storage as evidence, each 

animal was wrapped in aluminum foil, labeled as follows: species, identification number, and date. Upon 

wrapping and labeling, each animal was placed in a sealed plastic bag; transported to the wildlife triage 

building, and stored in a locked freezer. Chain of custody forms for the animal carcasses were completed 

daily and stored at the Wildlife Trailer. Another chain of custody was completed when each carcass was 

given to FWS Special Agents. One ruddy duck and and two muskrats were sent by the FWS to the 

National Fish and Wildlife Forensics Laboratory (NFWFL) in Ashland, Oregon for necropsy to 

determine cause of death. Copies of the necropsy reports are not available for release at this time. A 

daily morgue report was generated and accompanied the daily wildlife rehabilitation report that was 

distributed each morning (Appendix A and see Wildlife Rehabilitation Operations section). 

April 26, 2000 was the final date that the FWS had personnel operating the wildlife morgue. Following 

this date, TSBRR assumed these responsibilities. Wildlife morgue procedures remained the same under

TSBBR with the exception that all dead wildlife were brought to the wildlife triage center instead of the 

wastewater laboratory. On May 8, 2000 fish and invertebrate carcasses were photographed and the 

animals discarded. The decision to dispose of the fish and invertebrate carcasses was made by the U.S 

Attorney’s Office at the recommendation of the FWS. The purpose of the FWS recommendation to 

dispose of fish and invertebrate was related to available freezer space. Fish and invertebrates were by 

far the most abundant taxa brought into the morgue, and rapidly took up valuable freezer space. In 

addition, many deaths appeared unrelated to oil exposure. For example, many of the larger fish collected 

were gizzard shad and catfish (Table 3). These two species are commonly found dead along shorelines 

during the spring and summer months. 

The number of wildlife found dead in the field and brought to the morgue center was 804 individuals, 67% 

of which were fish (Table 3). It should be noted that hundreds of dead mummichogs were observed in 

tidal tributaries of Swanson Creek; however, only a subsample of these fish were collected (Table 3). 

Birds and mammals accounted for 17 % of the dead individuals. Ruddy ducks and muskrat were species 

that accounted for most deaths. Less than 3% of the collected dead wildlife were reptiles, most of which 

were diamondback terrapins and Northern watersnakes. As with fish, it should be noted that not all 

specimens collected were killed as a result of the spill. For example, the 3 otters that were collected 
5

appeared to have been dead before the spill took place, based on condition of the carcass at time of 

collection. Similarly, the three ospreys that were collected were not visibly oiled. Where possible, we 

have noted the number of collected animals that were not visibly oiled (Table 3, Appendix B). 

Endangered Species Issues

The section of Swanson Creek and Patuxent River impacted by the spill is also utilized by several pairs of 

nesting bald eagles, a federally listed endangered species. Six nests were identified within the spill zone, 

three of which were active during the spill. Two of the active nests were located near the mouth of 

Swanson Creek, one on the north shore slightly west of the PEPCO cooling towers, the other nest was 

located along the southern shoreline directly across from the cooling towers. The third active nest was 

located along Cremona Creek, which is located approximately 6 miles south of Swanson Creek. Both 

Swanson Creek nests failed to fledge young, however, fledging failure was not attributed to the oil spill. 

The Cremona Creek nest, however, did successfully fledge two eaglets. Monitoring of the 3 nests by FWS 

showed that the nest located along the southern shoreline of Swanson Creek did not have eggs or young 

despite the incubation posture exhibited by the adults. The second Swanson Creek nest did produce 

young, however, a wind storm blew the nest tree down during the spill, resulting in the death of the 

nestlings. During the monitoring period, nesting material was collected from each of the three active nests. 

The material did not appear oiled based on visual and olfactory inspection. Because overflights by 

helicopters, at least two a day, were conducted along the river to document oiling, in close proximity to 

eagle nests, the FWS requested that the Federal On Scene Coordinator (FOSC) contact the Federal 

Aviation Administration and issue a no fly zone along the western shoreline of the Patuxent River, and in an 

area near the mouth of Swanson Creek. The no fly zone included a minimal radius of 0.25 mile around 

each nest, and vertical distance of no less than 1,500 feet above each nest. The FWS also recommended 

that all low flying aircraft remain close to the eastern shoreline of the Patuxent River, where no active eagle 

nests are known to exist. A second federally listed endangered species, the puritan tiger beetle, is also 

present near the Patuxent River. However, FWS concerns for impacts to this species were minimal due to 

their presence near the mouth of the Patuxent River, a distance of approximately 20 miles from Swanson 

Creek. 

Identification of Environmentally Sensitive Areas

At the onset of the spill it was apparent that significant oiling of extensive tidal marshes had occurred in

Swanson Creek. In an effort to reduce further impacts to un-oiled marshes and other sensitive 

environments, the FWS along with personnel from MDNR’s Heritage program provided the FOSC with 

prioritized environmentally sensitive areas. Most of the identified sensitive areas were wetland habitats 

that fringed many of the tributaries entering the Patuxent River near the vicinity of Swanson Creek. These 

sensitive habitats were already identified in the Upper Chesapeake Estuary Area Contingency Plan and 

made prioritization a reasonably easy task. With the information provided to the FOSC, booming 

strategies were developed. Unfortunately, early in the spill several tidal marshes were identified as priority 

areas that needed booming (Indian and Trent Hall Creeks) were severely impacted by oil because of 
6

failure by contractors to boom these areas. Wetlands within Indian and Trent Hall Creek, excluding those 

in Swanson Creek, were two of the most impacted areas during the spill.
